For information regarding radio use in a hazardous atmosphere please refer to the Factory Mutual (FM) Approval Product Listing Manual or Instruction Card, which is included with radio models that offer this capability. Compliance with RF Energy Exposure Standards Your Motorola two-way radio is designed and tested to comply with a number of national and international standards and guidelines (listed below) regarding human exposure to radio frequency electromagnetic energy. This radio complies with the IEEE (FCC) and ICNIRP exposure limits for occupational/controlled RF exposure environment at duty cycles of up to 50% talk-50% listen and should be used for occupational use only. In terms of measuring RF energy for compliance with the FCC exposure guidelines, your radio radiates measurable RF energy only while it is transmitting (during talking), not when it is receiving (listening) or in standby mode. Note that the approved, supplied batteries for this radio are rated for a 5-5-90 duty cycle (5% talk - 5% listen - 90% standby), even though this radio complies with the FCC occupational exposure limits at duty cycles of up to 50% talk. Your Motorola two-way radio complies with the following RF energy exposure standards and guidelines: • • • • • • • United States Federal Communications Commission, Code of Federal Regulations; 47CFR part 2 sub-part J American National Standards Institute (ANSI) / Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1992 Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998 Ministry of Health (Canada) Safety Code 6. Limits of Human Exposure to Radio frequency Electromagnetic Fields in the Frequency Range from 3 kHz to 300 GHz, 1999 Australian Communications Authority Radiocommunications (Electromagnetic Radiation Human Exposure) Standard 2001 ANATEL, Brazil Regulatory Authority, Resolution 256 (April 11, 2001) “additional requirements for SMR, cellular and PCS product certification.” Operational Instructions and Training Guidelines To ensure optimal performance and compliance with the occupational/controlled environment RF energy exposure limits in the above standards and guidelines, users should transmit no more than 50% of the time and always adhere to the following procedures: Transmit and Receive To transmit (talk), push the Push-To-Talk (PTT) button; to receive, release the PTT button. Hand-held Radio Operation Hold the radio in a vertical position with the microphone one to two inches (2.5 to 5 cm) away from the lips. 2.5 to 5.0 cm (1 to 2 in.) Body-worn Operation Always place the radio in a Motorola approved clip, holder, holster, case, or body harness for this product. Use of non-Motorola-approved accessories may exceed FCC RF exposure guidelines. If you do not use a Motorola approved body-worn accessory and are not using the radio in the intended use position in front of the face, then ensure the antenna and the radio are kept 2.5 cm (one inch) from the body when transmitting. ii Antennas & Batteries Use only Motorola approved supplied antenna or Motorola approved replacement antenna. Unauthorized antennas, modifications, or attachments could damage the radio and may violate FCC regulations. Use only Motorola approved supplied batteries or Motorola approved replacement batteries. Use of non-Motorola-approved antennas or batteries may exceed FCC RF exposure guidelines. Approved Accessories For a list of approved Motorola accessories please contact your dealer, or local Motorola representative. ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY NOTE Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately shielded, designed, or otherwise configured for electromagnetic compatibility. Facilities To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in any facility where posted notices instruct you to do so. Hospitals or health care facilities may be using equipment that is sensitive to external RF energy. Aircraft When instructed to do so, turn off your radio when on board an aircraft. Any use of a radio must be in accordance with applicable regulations per airline crew instructions. Medical Devices • Pacemakers The Advanced Medical Technology Association (AdvaMed) recommends that a minimum separation of 6 inches (15 centimeters) be maintained between a handheld wireless radio and a pacemaker. These recommendations are consistent with those of the U.S. Food and Drug Administration. Persons with pacemakers should: • • • • • ALWAYS keep the radio more than 6 inches (15 centimeters) from their pacemaker when the radio is turned ON. not carry the radio in the breast pocket. use the ear opposite the pacemaker to minimize the potential for interference. turn the radio OFF immediately if you have any reason to suspect that interference is taking place. Hearing Aids Some digital wireless radios may interfere with some hearing aids. In the event of such interference, you may want to consult your hearing aid manufacturer to discuss alternatives. • Other Medical Devices If you use any other personal medical device, consult the manufacturer of your device to determine if it is adequately shielded from RF energy. Your physician may be able to assist you in obtaining this information. Driver Safety Check the laws and regulations on the use of radios in the area where you drive. Always obey them. When using your radio while driving, please: • • • Give full attention to driving and to the road. Use hands-free operation, if available. Pull off the road and park before making or answering a call if driving conditions so require. iii OPERATIONAL WARNINGS For Vehicles With an Air Bag Do not place a portable radio in the area over an air bag or in the air bag deployment area. Air bags inflate with great force. If a portable radio is placed in the air bag deployment area and the air bag inflates, the radio may be propelled with great force and cause serious injury to occupants of the vehicle. ! WARNING Potentially Explosive Atmospheres Turn off your radio prior to entering any area with a potentially explosive atmosphere, unless it is a radio type especially qualified for use in such areas as “Intrinsically Safe” (for example, Factory Mutual, CSA, UL, or CENELEC). Do not remove, install, or charge batteries in such areas. Sparks in a potentially explosive atmosphere can cause an explosion or fire resulting in bodily injury or even death. NOTE The areas with potentially explosive atmospheres referred to above include fueling areas such as below decks on boats, fuel or chemical transfer or storage facilities, and areas where the air contains chemicals or particles, such as grain, dust or metal powders. Areas with potentially explosive atmospheres are often but not always posted. Blasting Caps and Areas To avoid possible interference with blasting operations, turn off your radio when you are near electrical blasting caps, in a blasting area, or in areas posted: “Turn off two-way radio.” Obey all signs and instructions. OPERATIONAL CAUTIONS Antennas Do not use any portable radio that has a damaged antenna. If a damaged antenna comes into contact with your skin, a minor burn can result. ! Caution Batteries All batteries can cause property damage and/or bodily injury such as burns if a conductive material such as jewelry, keys, or beaded chains touch exposed terminals. The conductive material may complete an electrical circuit (short circuit) and become quite hot. Exercise care in handling any charged battery, particularly when placing it inside a pocket, purse, or other container with metal objects. iv v Table of Contents Section 1 Introduction 1.0 Scope of

If these checks are successfully completed, the radio will generate the Self-Test Pass Tone. If the self-test is not successful, a “bonk” is heard. Radios with displays are able to display these error messages: • • • • “RAM TST ERROR” for <RAM Test Error> “ROM CS ERROR” for <ROM Checksum Error> “EEPRM HW ERROR” for <EEPROM Hardware Test Error> “EEPRM CS ERROR” for <EEPROM Checksum Error> NOTE Radio without display emits only “bonk” (300 Hz) tone if it fails the self-test. Error Code Explanation Corrective Action “RAM TST ERROR” RAM Test Failure Retest radio by turning it off and turning it on again. If message reoccurs, replace RAM (U405). “ROM CS ERROR” ROM Checksum is wrong. Reprogram FLASH Memory, then retest. If message reoccurs, replace ROM (U406). “EEPRM HW ERROR” Codeplug structure mismatch, non existence of codeplug. Reprogram codeplug with correct version and retest radio. If message reoccurs, replace EEPROM (U407). “EEPRM CS ERROR” Codeplug checksum is wrong. Reprogram codeplug. No Display Display module is not connected properly. Display module is damaged. Check connection between main board and display module. Replace with new display module. 3-2 Error Codes 4-1 Section 4 CONTROLLER INFORMATION 1.0 Overview This section provides a detailed theory of operation for the radio and its components. 2.0 Radio Power Distribution Accessories 20 pin Connector Keypad/Option Board Audio PA Int/Ext Vdd Prime Expansion Board Switching Reg.

N N Figure 4-1: DC Power Distribution Block Diagram Figure 4-1 illustrates the DC distribution throughout the radio board. A 7.5V battery (BATT 7.5V) supplies power directly to the electronic on/off control as UNSWB+. When the radio is turned on, MECH_SWB+ (on/off/volume control) will trigger the electronic on/off control(momentary-on path), then SWB+ is distributed as shown in Figure 4-1. Vdda from 3.3V Vdda regulator will then supply the microprocessor. Data is then sent to ASFIC_CMP to turn on GCB4(DAC). GCB4 will take over the momentary-on path within 12ms. SWB+ will continue to support the whole board until the radio is turned off. Radio will be turned-off on two conditions; 1. MECH_SWB+ turned off 2. Low battery 4-2 Controller Board When low battery level is detected by the microprocessor through both conditions above, it will store the radio personality data to EEPROM before turning off. 3.0 Controller Board 3.1 General The controller board is the central interface between the various subsytems of the radio. It is separated into digital and audio architectures. The digital portion consists of a special Motorola microcontroller (HC11FL0). The audio power amplifier (Audio PA) and audio/signalling/filter/ companding IC (ASFIC_CMP) form the backbone of the audio/signalling architecture.

It covers the Conventional and Trunking portables. An open architecture system with the new HC11FL0 as the processor is used. Combinations of different size RAM, ROM and EEPROM are available for various application software. REAL TIME CLOCK (RTC) This radio supports Real Time Clock (RTC) module for purposes of Message Time Stamping and Time Keeping. The RTC module resides in the micro-processor HC11FL0. It is kept alive by a backup Lithium Ion battery when the primary battery is removed.

Clock frequency of 38.4kHz from a crystal oscillator provides the reference signal. In the processor, the frequency is divided down to 1Hz. As the RTC module is powered separately from the processor Vdd, the RTC is kept alive through the ModB / Vstby pin when the radio is switched off. A small button Lithium Ion battery continues to feed the RTC when the primary battery is removed. A MOSFET Q416 switches in the LiO supply when Vdd is removed. Q416 also provides isolation from BOOT_CTRL function in the event of radio program flashing. A small 3.3V regulator is used to charge the LiO battery. 4-4 Controller Board ModB/Vstby Supply Under various conditions, the supply to the ModB/Vstby would vary. Table 4-1 shows these conditions and circuits in operation. Table 4-1: ModB/Vstby Supply Modes Condition Circuit Operation Radio On Vdd supply voltage via CR411 Radio Off • Vdd turned off • Q416 gate is pulled low by R462 • Q416 is switched on • U410 supplies

5 KEYPAD BOARD INFORMATION Theory of Operation Keypad The LED_EN setting is set by the codeplug. When the value is set to high, the LED will not light up during power up and vice versa. U602 is a comparator that will compare the voltage when any one of the keypad row or keypad column keys is being pressed. Therefore when a key is being pressed, it will send a message to the microprocessor through the output (KEY_INT) telling it that a key has been pressed. The microprocessor will then sample the Analog to Digital voltages at the keypad row and keypad column and map it with the table so that the key being pressed can be identified. Once the key has been identified, the message that corresponds to the key will show up at the display. 18 pin connector Data Display 1.0 Keypad Column 40 pin connector Keypad Row Key_Int LED

PRF1507 LDMOS PA (Q110). The 9Z67 LDMOS driver IC contains a 2 stage amplification with a supply voltage of 7.3V. This RF power amplifier is capable of supplying an output power of 0.3W (pin 6 and 7) with an input signal of 2mW (3dBm) (pin16). The current drain would typically be 160mA while operating in the frequency range of 403-470MHz. The PRF1507 LDMOS PA is capable of supplying an output power of 7W with an input signal of 0.3W. The current drain would typically be 1300mA while operating in the frequency range of 403470MHz. The power output can be varied by changing the biasing voltage. Transmitter 6A-5 3.1.2 Antenna Switch The antenna switch circuit consists of two PIN diodes (CR101 and CR102), a pi network (C107, L104 and C106), and two current limiting resistors (R101, R170). In the transmit mode, B+ at PCIC (U102) pin 23 will go low and turn on Q111 where a B+ bias is applied to the antenna switch circuit to bias the diodes "on". The shunt diode (CR102) shorts out the receiver port, and the pi network, which operates as a quarter wave transmission line, transforms the low impedance of the shunt diode to a high impedance at the input of the harmonic filter. In the receive mode, the diodes are both off, and hence, there exists a low attenuation path between the antenna and receiver ports. 3.1.3 Harmonic Filter The harmonic filter consists of C104, L102, C103, L101 and C102. The design of the harmonic filter for UHF is that of a modified Zolotarev design. It has been optimized for efficiency of the power module. This type of filter has the advantage that it can give a greater attenuation in the stop-band for a given ripple level. The harmonic filter insertion loss is typically less than 1.2dB. 3.1.4 Antenna Matching Network A matching network which is made up of L116 is used to match the antenna's impedance to the harmonic filter. This will optimize the performance of the transmitter and receiver into an antenna. 3.1.5 Power Control Integrated Circuit (PCIC) The transmitter uses the Power Control IC (PCIC), U102 to regulate the power output of the radio. The current to the final stage of the power module is supplied through R101, which provides a voltage proportional to the current drain. This voltage is then fedback to the Automatic Level Control (ALC) within the PCIC to regulate the output power of the transmitter. The PCIC has internal digital to analog converters (DACs) which provide the reference voltage of the control loop. The reference voltage level is programmable through the SPI line of the PCIC. There are resistors and integrators within the PCIC, and external capacitors (C133, C134 and C135) in controlling the transmitter rising and falling time. These are necessary in reducing the power splatter into adjacent channels. CR105 and its associated components are part of the temperature cut back circuitry. It senses the printed circuit board temperature around the transmitter circuits and output a DC voltage to the PCIC. If the DC voltage produced exceeds the set threshold in the PCIC, the transmitter output power will be reduced so as to reduce the transmitter temperature. 6A-6 4.0 Receiver Receiver Antenna RF Jack Pin Diode Antenna Switch Varactor Tuned Filter RF Amp Varactor Tuned Filter Mixer Crystal Filter IF Amp AGC Control Voltage from ASFIC First LO from FGU Recovered Audio Squelch Demodulator U301 RSSI IF IC Synthesizer 16.8 MHz Reference Clock SPI Bus Second LO VCO Figure 6-2: UHF Receiver Block Diagram 4.1 Receiver Front-End (Refer to UHF Receiver Front End Schematic Diagram on page 6A-18 and UHF Transmitter Schematic Diagram on page 6A-22) The RF signal is received by the antenna and applied to a low-pass filter. For UHF, the filter consists of L101, L102, C102, C103, C104. The filtered RF signal is passed through the antenna switch. The antenna switch circuit consists of two PIN diodes(CR101 and CR102) and a pi network (C106, L104 and C107).The signal is then applied to a varactor tuned bandpass filter. The UHF bandpass filter comprises of L301, L302, C302, C303, C304, CR301 and CR302. The bandpass filter is tuned by applying a control voltage to the varactor diodes(CR301 and CR302) in the filter. The bandpass filter is electronically tuned by the DACRx from IC404 which is controlled by the microprocessor. Depending on the carrier frequency, the DACRx will supply the tuned voltage to the varactor diodes in the filter. Wideband operation of the filter is achieved by shifting the bandpass filter across the band. The output of the bandpass filter is coupled to the RF amplifier transistor Q301 via C307. After being amplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned bandpass filter, consisting of L306, L307, C313, C317, CR304 and CR305. Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidth of the filter is about 50 MHz. This enables the filters to be electronically controlled by using a single control voltage which is DACRx . Receiver 6A-7 The output of the post-RF amplifier filter which is connected to the passive double balanced mixer consists of T301, T302 and CR306. Matching of the filter to the mixer is provided by C381. After mixing with the first LO signal from the voltage controlled oscillator (VCO) using low side injection, the RF signal is down-converted to the 45.1 MHz IF signal. The IF signal coming out of the mixer is transfered to the crystal filter (FL301) through a resistor pad and a diplexer (C322 and L310). Matching to the input of the crystal filter is provided by C324 and L311. The crystal filter provides the necessary selectivity and intermodulation protection. 4.2 Receiver Back-End (Refer to UHF Receiver Back End Schematic Diagram on page 6A-19) The output of crystal filter FL301 is matched to the input of IF amplifier transistor Q302 by components R352 and C325. Voltage supply to the IF amplifier is taken from the receive 5 volts (R5). The IF amplifer provides a gain of about 7dB. The amplified IF signal is then coupled into U301(pin 3) via C330, C338 and L330 which provides the matching for the IF amplifier and U301. The IF signal applied to pin 3 of U301 is amplified, down-converted, filtered, and demodulated, to produce the recovered audio at pin 27 of U301. This IF IC is electronically programmable, and the amount of filtering (which is dependent on the radio channel spacing) is controlled by the microprocessor. Additional filtering, once externally provided by the conventional ceramic filters, is replaced by internal filters in the IF module (U301). The IF IC uses a type of direct conversion process, whereby the externally generated second LO frequency is divided by two in U301 so that it is very close to the first IF frequency. The IF IC (U301) synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LO is designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IF IC. In the absence of an IF signal, the VCO will “search” for a frequency, or its frequency will vary close to twice the IF frequency. When an IF signal is received, the VCO will lock onto the IF signal. The second LO/VCO is a Colpitts oscillator built around transistor Q320. The VCO has a varactor diode, CR310, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filter consisting of C362, C363, C364, R320 and R321. The IF IC (U301) also performs several other functions. It provides a received signal-strength indicator (RSSI) and a squelch output. The RSSI is a dc voltage monitored by the microprocessor, and used as a peak indicator during the bench tuning of the receiver front-end varactor filter. The RSSI voltage is also used to control the automatic gain control (AGC) circuit at the front-end. The demodulated signal on pin 27 of U301 is also used for squelch control. The signal is routed to U404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audio signal is also routed to U404 for processing before going to the audio amplifier for amplification. 6A-8 4.3 Receiver Automatic Gain Control Circuit (Refer to UHF Receiver Front End Schematic Diagram on page 6A-18) The front end automatic gain control circuit is to provide automatic gain reduction of the front end RF amplifier via feedback. This action is necessary to prevent overloading of backend circuits. This is achieved by drawing some of the output power from the RF amplifier’s output. At high radio frequencies, capacitor C331 provides the low impedance path to ground for this purpose. CR308 is a PIN diode used for switching the path on or off. A certain amount of forward biasing current is needed to turn the PIN diode on. Transistors Q315 provides this current where upon saturation, current will flow via R347, PIN diode, collector and emitter of Q315 and R319 before going to ground. Q315 is an NPN transistor used for switching here. Maximum current flowing through the PIN is mainly limited by the resistor R319. Radio signal strength indicator, RSSI, a voltage signal, is used to drive Q315 to saturation hence turning it on. RSSI is produced by U301 and is proportional to the gain of the RF amplifier and the input RF signal power to the radio. Resistor network at the input to the base of Q315 is scaled to turn on Q315, hence activating the AGC, at certain RSSI levels. In order to turn on Q315, the voltage across the transistor’s base to ground must be greater or equal to the voltage across R319, plus the base-emitter voltage (Vbe) present at Q315. The resistor network with thermistor RT300 is capable of providing temperature compensation to the AGC circuit, as RSSI generated by U301 is lower at cold temperatures compared to normal operation at room temperature. Resistor R300 and capacitor C397 form an R-C network used to dampen any transient instability while the AGC is turning on.

Rx VCO Circuit Aux4 Loop Filter MOD Out Rx Out Matching Network Low Pass Filter Attenuator To PA Driver To Mixer VCOBIC U241 Tx Out Tx VCO Circuit Modulating Signal Figure 6-3: Frequency Generation Unit Block Diagram The Frequency Generation Circuitry is composed of two main ICs, the Fractional-N synthesizer (U201), and the VCO/Buffer IC (U241). Designed in conjunction to maximize compatibility, the two ICs provide many of the functions that normally would require additional circuitry. The synthesizer block diagram illustrates the interconnect and support circuitry used in the region. Refer to the relevant schematics for the reference designators. The synthesizer is powered by regulated 5V and 3.3V which come from U247 and U248 respectively. The synthesizer in turn generates a superfiltered 4.5V which powers U241. In addition to the VCO, the synthesizer must interface with the logic and ASFIC circuitry. Programming for the synthesizer is accomplished through the data , clock and chip select lines from the microprocessor. A 3.3V dc signal from synthesizer lock detect line indicates to the microprocessor that the synthesizer is locked. Transmit modulation from the ASFIC is supplied to pin10 of U201. Internally the audio is digitized by the Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runs through an internal attenuator for modulation balancing purposes before going out to the VCO. 6A-10 5.1 Frequency Generation Circuitry Synthesizer (Refer to UHF Synthesizer Schematic Diagram on page 6A-20) The Fractional-N Synthesizer uses a 16.8MHz crystal (FL201) to provide a reference for the system. The LVFractN IC (U201) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as reference frequencies. Together with C206, C207, C208, R204 and CR203 , they build up the reference oscillator which is capable of 2.5ppm stability over temperatures of -30 to 85°C. It also provides 16.8MHz at pin 19 of U201 to be used by ASFIC and LVZIF. The loop filter which consist of C231, C232, C233, R231, R232 and R233 provides the necessary dc steering voltage for the VCO and determines the amount of noise and spur passing through . In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current at pin 45 of U201 to put synthesizer within the lock range. The required frequency is then locked by normal mode charge pump at pin 43 . Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier which is made up of C258, C259, C228, triple diode CR201 and level shifters U210 and U211. Two 3.3V square waves ( 180 deg out of phase) are first shifted to 5V, then along with regulated 5V , put through arrays of diodes and capacitors to build up 13.3V at pin 47 of U201. 8 9 CSX (U409 PIN 2) 10 MOD IN (U404 PIN 40) 13, 30 (U248 PIN 5) 4 LOCK (U409 PIN 56) FREFOUT 19 FREF (U201 PIN 21 & U404 PIN 34) DATA CLOCK (U409 PIN 1) +5V (U247 PIN 4) LOCK 7 DATA (U409 PIN 100) 5, 20, 34, 36 23 REFERENCE OSCILLATOR 24 25 32 47 VOLTAGE MULTIPLIER CLK GND U251 LOW VOLTAGE MODIN FRACTIONAL-N IOUT SYNTHESIZER IADAPT VCC, DC5V MODOUT V , 3.3V 6, 22, 23, 24 CEX DD STEERING LINE 43 45 41 XTAL1 AUX4 3 XTAL2 AUX3 2 WARP SFOUT 2-POLE LOOP FILTER LO RF INJECTION DUAL TRANSIS TORS 28 FILTERED 5V PREIN BIAS1 VCP VMULT2 14 VOLTAGE CONTROLLED OSCILLATOR 40 VMULT1 AUX1 BIAS2 TX RF INJECTION (1ST STAGE OF PA) 39 15 48 DUAL 5V TRANSISTORS R5 PRESCALER IN Figure 6-4 Synthesizer Block Diagram Frequency Generation Circuitry 5.2 6A-11 VCO - Voltage Controlled Oscillator (Refer to UHF Voltage Controlled Oscillator Schematic Diagram on page 6A-21) 5V AUX3 (U201 Pin2) Level Shifter Network AUX4 (U201 Pin3) U201 Pin 32 Prescaler Out TRB_IN Pin 20 Rx-SW Pin7 Tx-SW Pin13 Pin 19 Pin 12 TX/RX/BS Switching Network LO RF INJECTION (U201 Pin28) VSF Steer Line Voltage (VCTRL) Vcc-Superfilter Pin3 Presc Matching Network U241 VCOBIC Low Pass Filter Collector/RF in Pin4 RX RX RX Tank RX VCO Circuit Rx Active Bias Pin5 Pin8 VSF (U201 Pin28) Pin14 Pin6 TX TX Tank TX VCO Circuit Tx Active Bias Pin16 TX Pin10 VCC Buffers TX RF Injection Attenuator Pin15 Vsens Circuit Pin18 Vcc-Logic Pin2 Pin1 Rx-I adjust Tx-I adjust Pins 9,11,17 VSF (U201 Pin28) Figure 6-5 VCO Block Diagram The VCOBIC (U241) in conjunction with the Fractional-N synthesizer (U201) generates RF in both the receive and the transmit modes of operation. The TRB line (U241 pin 19) determines which oscillator and buffer will be enabled. A sample of the RF signal from the enabled oscillator is routed from U241 pin 12, through a low pass filter, to the prescaler input (U201 pin 32). After frequency comparison in the synthesizer, a resultant CONTROL VOLTAGE is received at the VCO. This voltage is a DC voltage between 3.5V and 9.5V when the PLL is locked on frequency. 6A-12 Frequency Generation Circuitry The VCOBIC(U241) is operated at 4.54 V (VSF) and Fractional-N synthesizer (U201) at 3.3V. This difference in operating voltage requires a level shifter consisting of Q260 and Q261 on the TRB line. The operation logic is shown in Table 6-1. Table 6-1: Level Shifter Logic Desired Mode AUX 4 AUX 3 TRB Tx Low High (@3.2V) High (@4.8V) Rx High Low Low Battery Saver Low Low Hi-Z/Float (@2.5V) In the receive mode, U241 pin 19 is low or grounded. This activates the receive VCO by enabling the receive oscillator and the receive buffer of U241. The RF signal at U241 pin 8 is run through a matching network. The resulting RF signal is the LO RF INJECTION and it is applied to the mixer at T302 (refer to UHF Receiver Front End Schematic Diagram on page 6A-18). During the transmit condition, when PTT is depressed, five volts is applied to U241 pin 19. This activates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U241. The RF signal at U241 pin 10 is injected into the input of the PA module (U101 pin16). This RF signal is the TX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto the carrier is received through the U201 pin 41. When a high impedance is applied to U241 pin19, the VCO is operating in BATTERY SAVER mode. In this case, both the receive and transmit oscillators as well as the receive transmit and prescaler buffer are turned off.

PRF1507 LDMOS PA (Q3501). The 9Z67 LDMOS driver IC contains a 2 stage amplification with a supply voltage of 7.3V. This RF power amplifier is capable of supplying an output power of 0.3W (pin 6 and 7) with an input signal of 2mW (3dBm) (pin16). The current drain would typically be 130mA while operating in the frequency range of 136-174MHz. The PRF1507 LDMOS PA is capable of supplying an output power of 7W with an input signal of 0.3W. The current drain would typically be 1800mA while operating in the frequency range of 136-174MHz. The power output can be varied by changing the biasing voltage. Transmitter 6B-5 3.1.2 Antenna Switch The antenna switch circuit consists of two PIN diodes (D3521 and D3551), a pi network (C3531, L3551 and C3550), and three current limiting resistors (R3571, R3572, R3573 ). In the transmit mode, B+ at PCIC (U3502) pin 23 will go low and turn on Q3561 where a B+ bias is applied to the antenna switch circuit to bias the diodes "on". The shunt diode (D3551) shorts out the receiver port, and the pi network, which operates as a quarter wave transmission line, transforms the low impedance of the shunt diode to a high impedance at the input of the harmonic filter. In the receive mode, the diodes are both off, and hence, there exists a low attenuation path between the antenna and receiver ports. 3.1.3 Harmonic Filter The harmonic filter consists of C3532 to C3536, L3531 and L3532. This network forms a low-pass filter to attenuate harmonic energy of the transmitter to specifications level. The harmonic filter insertion loss should be less than 1.2dB. 3.1.4 Antenna Matching Network A matching network which is made up of L3538 and C3537 is used to match the antenna's impedance to the harmonic filter. This will optimize the performance of the transmitter and receiver into an antenna. 3.1.5 Power Control Integrated Circuit (PCIC) The transmitter uses the Power Control IC (PCIC), U3502 to control the power output of the radio by maintaining the radio current drain. The current to the final stage of the power module is supplied through R3519 (0.1ohms), which provides a voltage proportional to the current drain. This voltage is then fedback to the Automatic Level Control (ALC) within the PCIC to keep the whole loop stable. The PCIC has internal digital to analog converters (DACs) which provide the reference voltage of the control loop. The voltage level is controlled by the microprocessor through the data line of the PCIC. There are resistors and integrators within the PCIC, and external capacitors (C3562, C3563 and C3565) in controlling the transmitter rising and falling time. These are necessary in reducing the power splatter into adjacent channels. U3503 and its associated circuitry acts as a temperature cut back circuitry. This circuitry provides the necessary voltage to the PCIC to cut the transmitter power when the radio temperature gets too high. 6B-6 4.0 Receiver Receiver Antenna RF Jack Pin Diode Antenna Switch Varactor Tuned Filter RF Amp Varactor Tuned Filter Mixer Crystal Filter IF Amp AGC Control Voltage from ASFIC First LO from FGU Recovered Audio Squelch Demodulator U3220 RSSI IF IC Synthesizer 16.8 MHz Reference Clock SPI Bus Second LO VCO Figure 6-2: VHF Receiver Block Diagram 4.1 Receiver Front-End (Refer toVHF Receiver Front End Schematic Diagram on page 6B-20, VHF Receiver Back End Schematic Diagram on page 6B-21, and VHF Transmitter Schematic Diagram on page 6B-24) The RF signal is received by the antenna and applied to a low-pass filter. For VHF, the filter consists of L3531, L3532, C3532 to C3563. The filtered RF signal is passed through the antenna switch. The antenna switch circuit consists of two PIN diodes(D3521 and D3551) and a pi network (C3531, L3551 and C3550).The signal is then applied to a varactor tuned bandpass filter. The VHF bandpass filter comprises of L3301, L3303, C3301 to C3304 and D3301. The bandpass filter is tuned by applying a control voltage to the varactor diode (D3301) in the filter. The bandpass filter is electronically tuned by the DACRx from IC404 which is controlled by the microprocessor. Depending on the carrier frequency, the DACRx will supply the tuned voltage to the varactor diodes in the filter. Wideband operation of the filter is achieved by shifting the bandpass filter across the band. The output of the bandpass filter is coupled to the RF amplifier transistor Q3302 via C3306. After being amplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned bandpass filter, consisting of L3305, L3306, C3311 to C3314 and D3302. Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidth of the filter is about 12 MHz. This enables the filters to be electronically controlled by using a single control voltage which is DACRx . Receiver 6B-7 The output of the post-RF amplifier filter is connected to the passive double balanced mixer which consists of T3301, T3302 and CR3301. Matching of the filter to the mixer is provided by C3317, C3318 and L3308. After mixing with the first LO signal from the voltage controlled oscillator (VCO) using high side injection, the RF signal is down-converted to the 45.1 MHz IF signal. The IF signal coming out of the mixer is transfered to the crystal filter (Y3200) through a resistor pad (R3321 - R3323) and a diplexer (C3320 and L3309). Matching to the input of the crystal filter is provided by C3200 and L3200. The crystal filter provides the necessary selectivity and intermodulation protection. 4.2 Receiver Back-End (Refer to VHF Receiver Back End Schematic Diagram on page 6B-21) The output of crystal filter Y3200 is matched to the input of IF amplifier transistor Q3200 by capacitor C3203. Voltage supply to the IF amplifier is taken from the receive 5 volts (R5). The gain controlled IF amplifer provides a maximum gain of about 10dB. The amplified IF signal is then coupled into U3220(pin 3) via L3202, C3207, and C3230 which provides the matching for the IF amplifier and U3220. The IF signal applied to pin 3 of U3220 is amplified, down-converted, filtered, and demodulated, to produce the recovered audio at pin 27 of U3220. This IF IC is electronically programmable, and the amount of filtering (which is dependent on the radio channel spacing) is controlled by the microprocessor. Additional filtering, once externally provided by the conventional ceramic filters, is replaced by internal filters in the IF module (U3220). The IF IC uses a type of direct conversion process, whereby the externally generated second LO frequency is divided by two in U3220 so that it is very close to the first IF frequency. The IF IC (U3220) synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LO is designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IF IC. In the absence of an IF signal, the VCO will “search” for a frequency, or its frequency will vary close to twice the IF frequency. When an IF signal is received, the VCO will lock onto the IF signal. The second LO/VCO is a Colpitts oscillator built around transistor Q3270. The VCO has a varactor diode, D3270, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filter consisting of C3278 to C3280, R3274 and R3275. The IF IC (U3220) also performs several other functions. It provides a received signal-strength indicator (RSSI) and a squelch output. The RSSI is a dc voltage monitored by the microprocessor, and used as a peak indicator during the bench tuning of the receiver front-end varactor filter. The RSSI voltage is also used to control the automatic gain control (AGC) circuit at the front-end. The demodulated signal on pin 27 of U3220 is also used for squelch control. The signal is routed to U404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audio signal is also routed to U404 for processing before going to the audio amplifier for amplification. 6B-8 4.3 Receiver Automatic Gain Control Circuit (Refer to VHF Receiver Front End Schematic Diagram on page 6B-20 and VHF Receiver Back End Schematic Diagram on page 6B-21) The front end automatic gain control circuit provides automatic reduction of gain, of the front end RF amplifier via feedback. This action is necessary to prevent overloading of backend circuits. This is achieved by drawing some of the output power from the RF amplifier output. At high radio frequencies, capacitor C3327 provides the low impedance path to ground for this purpose. CR3302 is a PIN diode used for switching the path on or off. A certain amount of forward biasing current is needed to turn the PIN diode on. Transistor Q3301 provides this current. Radio signal strength indicator, RSSI, a voltage signal, is used to drive Q3301 to saturation i.e. turned on. RSSI is produced by U3220 and is proportional to the gain of the RF amplifier and the input power to the radio. Resistors R3304 and R3305 are voltage dividers designed to turn on Q3301 at certain RSSI levels. In order to turn on Q3301 the voltage across R3305 must be greater or equal to the voltage across R3324, plus the base-emitter voltage (Vbe) present at Q3301. Capacitor C3209 is used to dampen any instability while the AGC is turning on. The current flowing into the collector of Q3301, a high current gain NPN transistor, will be drawn through the PIN diode to turn it on. Maximum current flowing through the PIN is limited by the resistors R3316, R3313, R3306 and R3324. C3326 is a feedback capacitor used to provide some stability to this high gain stage. An additional gain control circuit is formed by Q3201 and its associated circuitry. Resistors R3206 and R3207 are voltage dividers designed to turn on Q3201 at a significantly higher RSSI level than the level required to turn on PIN diode control transistor Q3301. In order to turn on Q3201 the voltage across R3207 must be greater or equal to the voltage across R3208, plus the base-emitter voltage (Vbe) present at Q3201. As current starts flowing into the collector of Q3201, it reduces the bias voltage at the base of IF amplifier transistor Q3200 and in turn, the gain of the IF amplifier. The gain can be controlled in a range of -30dB up to +10dB.

MOD Out Rx VCO Circuit Loop Filter Rx Out To Mixer VCOBIC U3801 Tx Out To PA Driver Tx VCO Circuit Modulating Signal Figure 6-3: Frequency Generation Unit Block Diagram The Frequency Generation Circuitry is composed of two main ICs, the Fractional-N synthesizer (U3701), and the VCO/Buffer IC (U3801). Designed in conjunction to maximize compatibility, the two ICs provide many of the functions that normally would require additional circuitry. The synthesizer block diagram illustrates the interconnect and support circuitry used in the region. Refer to the relevant schematics for the reference designators. The synthesizer is powered by regulated 5V and 3.3V which come from U3711 and U3201 respectively. The synthesizer in turn generates a superfiltered 4.5V which powers U3801. In addition to the VCO, the synthesizer must interface with the logic and ASFIC circuitry. Programming for the synthesizer is accomplished through the data , clock and chip select lines from the microprocessor. A 3.3V dc signal from synthesizer lock detect line indicates to the microprocessor that the synthesizer is locked. Transmit modulation from the ASFIC is supplied to pin10 of U3701. Internally the audio is digitized by the Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runs through an internal attenuator for modulation balancing purposes before going out to the VCO. 6B-10 5.1 Frequency Generation Circuitry Synthesizer (Refer toVHF Synthesizer Schematic Diagram on page 6B-22) The Fractional-N Synthesizer uses a 16.8MHz crystal (Y3761) to provide a reference for the system. The LVFractN IC (U3701) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as reference frequencies. Together with C3761, C3762, C3763, R3761 and D3761 , they build up the reference oscillator which is capable of 2.5ppm stability over temperatures of -30 to 85°C. It also provides 16.8MHz at pin 19 of U3701 to be used by ASFIC and LVZIF. The loop filter which consist of C3721, C3722, R3721, R3722 and R3723 provides the necessary dc steering voltage for the VCO and determines the amount of noise and spur passing through . In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current at pin 45 of U3701 to put synthesizer within the lock range. The required frequency is then locked by normal mode charge pump at pin 43 . Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier which is made up of C3701 to C3704 and triple diodes D3701, D3702. Two 3.3V square waves ( 180 deg out of phase) are first multiplied by four and then shifted, along with regulated 5V, to build up 13.5V at pin 47 of U3701.

The TRB line (U3801 pin 19) determines which oscillator and buffer will be enabled. A sample of the RF signal from the enabled oscillator is routed from U3801 pin 12, through a low pass filter, to the prescaler input (U3701 pin 32). After frequency comparison in the synthesizer, a resultant CONTROL VOLTAGE is received at the VCO. This voltage is a DC voltage typically between 3.5V and 9.5V when the PLL is locked on frequency. 6B-12 Frequency Generation Circuitry The RF section of the VCOBIC(U3801) is operated at 4.54 V (VSF), while the control section of the VCOBIC and Fractional-N synthesizer (U3701) is operated at 3.3V. The operation logic is shown in Table 6-1. Table 6-1: VCO Control Logic Desired Mode AUX 4 AUX 3 TRB Tx n.u. High (@3.2V) High (@3.2V) Rx n.u. Low Low Battery Saver n.u. Hi-Z/Float (@1.6V) Hi-Z/Float (@1.6V) In the receive mode, U3801 pin 19 is low or grounded. This activates the receive VCO by enabling the receive oscillator and the receive buffer of U3801. The RF signal at U3801 pin 8 is run through a matching network. The resulting RF signal is the LO RF INJECTION and it is applied to the mixer at T3302. During the transmit condition, when PTT is depressed, 3.2 volts is applied to U3801 pin 19. This activates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U3801. The RF signal at U3801 pin 10 is injected into the input of the PA module (U3501 pin16). This RF signal is the TX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto the carrier is received through U3701 pin 41. When a high impedance is applied to U3801 pin19, the VCO is operating in BATTERY SAVER mode. In this case, both the receive and transmit oscillators as well as the receive transmit and prescaler buffer are turned off.

Transmitter 3.0 6C-3 Transmitter P CI C From VCO Antenna Jack Vcontrol Vcontrol PA Driver PA-Final Stage Antenna Switch/ Harmonic Filter/ Matching Network Figure 6-1: Transmitter Block Diagram 3.1 General (Refer to Figure 6-1) The UHF transmitter contains five basic circuits: 1. power amplifier 2. antenna switch 3. harmonic filter 4. antenna matching network 5. power control integrated circuit (PCIC). 3.1.1 Power Amplifier The power amplifier consists of two devices: 1. 9Z67 LDMOS driver IC (U101) and 2. PRF1507 LDMOS PA (Q110). The 9Z67 LDMOS driver IC contains a 2 stage amplification with a supply voltage of 7.3V. This RF power amplifier is capable of supplying an output power of 0.3W (pin 6 and 7) with an input signal of 2mW (3dBm) (pin16). The current drain would typically be 160mA while operating in the frequency range of 450-527MHz. The PRF1507 LDMOS PA is capable of supplying an output power of 7W with an input signal of 0.3W. The current drain would typically be 1300mA while operating in the frequency range of 450527MHz. The power output can be varied by changing the biasing voltage. 6C-4 Transmitter 3.1.2 Antenna Switch The antenna switch circuit consists of two PIN diodes (CR101 and CR102), a pi network (C107, L104 and C106), and two current limiting resistors (R101, R170). In the transmit mode, B+ at PCIC (U102) pin 23 will go low and turn on Q111 where a B+ bias is applied to the antenna switch circuit to bias the diodes "on". The shunt diode (CR102) shorts out the receiver port, and the pi network, which operates as a quarter wave transmission line, transforms the low impedance of the shunt diode to a high impedance at the input of the harmonic filter. In the receive mode, the diodes are both off, and hence, there exists a low attenuation path between the antenna and receiver ports. 3.1.3 Harmonic Filter The harmonic filter consists of C104, L102, C103, L101 and C102. The design of the harmonic filter for UHF is that of a modified Zolotarev design. It has been optimized for efficiency of the power module. This type of filter has the advantage that it can give a greater attenuation in the stop-band for a given ripple level. The harmonic filter insertion loss is typically less than 1.2dB. 3.1.4 Antenna Matching Network A matching network which is made up of L116 is used to match the antenna's impedance to the harmonic filter. This will optimize the performance of the transmitter and receiver into an antenna. 3.1.5 Power Control Integrated Circuit (PCIC) The transmitter uses the Power Control IC (PCIC), U102 to regulate the power output of the radio. The current to the final stage of the power module is supplied through R101, which provides a voltage proportional to the current drain. This voltage is then fedback to the Automatic Level Control (ALC) within the PCIC to regulate the output power of the transmitter. The PCIC has internal digital to analog converters (DACs) which provide the reference voltage of the control loop. The reference voltage level is programmable through the SPI line of the PCIC. There are resistors and integrators within the PCIC, and external capacitors (C133, C134 and C135) in controlling the transmitter rising and falling time. These are necessary in reducing the power splatter into adjacent channels. CR105 and its associated components are part of the temperature cut back circuitry. It senses the printed circuit board temperature around the transmitter circuits and output a DC voltage to the PCIC. If the DC voltage produced exceeds the set threshold in the PCIC, the transmitter output power will be reduced so as to reduce the transmitter temperature.

For UHF, the filter consists of L101, L102, C102, C103, C104. The filtered RF signal is passed through the antenna switch. The antenna switch circuit consists of two PIN diodes(CR101 and CR102) and a pi network (C106, L104 and C107).The signal is then applied to a varactor tuned bandpass filter. The UHF bandpass filter comprises of L301, L302, C302, C303, C304, CR301 and CR302. The bandpass filter is tuned by applying a control voltage to the varactor diodes(CR301 and CR302) in the filter. The bandpass filter is electronically tuned by the DACRx from IC404 which is controlled by the microprocessor. Depending on the carrier frequency, the DACRx will supply the tuned voltage to the varactor diodes in the filter. Wideband operation of the filter is achieved by shifting the bandpass filter across the band. The output of the bandpass filter is coupled to the RF amplifier transistor Q301 via C307. After being amplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned bandpass filter, consisting of L306, L307, C313, C317, CR304 and CR305. Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidth of the filter is about 50 MHz. This enables the filters to be electronically controlled by using a single control voltage which is DACRx . 6C-6 Receiver The output of the post-RF amplifier filter which is connected to the passive double balanced mixer consists of T301, T302 and CR306. Matching of the filter to the mixer is provided by C381. After mixing with the first LO signal from the voltage controlled oscillator (VCO) using low side injection, the RF signal is down-converted to the 45.1 MHz IF signal. The IF signal coming out of the mixer is transfered to the crystal filter (FL301) through a resistor pad and a diplexer (C322 and L310). Matching to the input of the crystal filter is provided by C324 and L311. The crystal filter provides the necessary selectivity and intermodulation protection. 4.2 Receiver Back-End (Refer to UHF Band 2 Receiver Back End Schematic Diagram on page 6C-17) The output of crystal filter FL301 is matched to the input of IF amplifier transistor Q302 by components R352 and C325. Voltage supply to the IF amplifier is taken from the receive 5 volts (R5). The IF amplifer provides a gain of about 7dB. The amplified IF signal is then coupled into U301(pin 3) via C330, C338 and L330 which provides the matching for the IF amplifier and U301. The IF signal applied to pin 3 of U301 is amplified, down-converted, filtered, and demodulated, to produce the recovered audio at pin 27 of U301. This IF IC is electronically programmable, and the amount of filtering (which is dependent on the radio channel spacing) is controlled by the microprocessor. Additional filtering, once externally provided by the conventional ceramic filters, is replaced by internal filters in the IF module (U301). The IF IC uses a type of direct conversion process, whereby the externally generated second LO frequency is divided by two in U301 so that it is very close to the first IF frequency. The IF IC (U301) synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LO is designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IF IC. In the absence of an IF signal, the VCO will “search” for a frequency, or its frequency will vary close to twice the IF frequency. When an IF signal is received, the VCO will lock onto the IF signal. The second LO/VCO is a Colpitts oscillator built around transistor Q320. The VCO has a varactor diode, CR310, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filter consisting of C362, C363, C364, R320 and R321. The IF IC (U301) also performs several other functions. It provides a received signal-strength indicator (RSSI) and a squelch output. The RSSI is a dc voltage monitored by the microprocessor, and used as a peak indicator during the bench tuning of the receiver front-end varactor filter. The RSSI voltage is also used to control the automatic gain control (AGC) circuit at the front-end. The demodulated signal on pin 27 of U301 is also used for squelch control. The signal is routed to U404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audio signal is also routed to U404 for processing before going to the audio amplifier for amplification. Receiver 4.3 6C-7 Automatic Gain Control Circuit (Refer to UHF Band 2 Receiver Front End Schematic Diagram on page 6C-16) The front end automatic gain control circuit is to provide automatic gain reduction of the front end RF amplifier via feedback. This action is necessary to prevent overloading of backend circuits. This is achieved by drawing some of the output power from the RF amplifier’s output. At high radio frequencies, capacitor C331 provides the low impedance path to ground for this purpose. CR308 is a PIN diode used for switching the path on or off. A certain amount of forward biasing current is needed to turn the PIN diode on. Transistors Q315 provides this current where upon saturation, current will flow via R347, PIN diode, collector and emitter of Q315 and R319 before going to ground. Q315 is an NPN transistor used for switching here. Maximum current flowing through the PIN is mainly limited by the resistor R319. Radio signal strength indicator, RSSI, a voltage signal, is used to drive Q315 to saturation hence turning it on. RSSI is produced by U301 and is proportional to the gain of the RF amplifier and the input RF signal power to the radio. Resistor network at the input to the base of Q315 is scaled to turn on Q315, hence activating the AGC, at certain RSSI levels. In order to turn on Q315, the voltage across the transistor’s base to ground must be greater or equal to the voltage across R319, plus the base-emitter voltage (Vbe) present at Q315. The resistor network with thermistor RT300 is capable of providing temperature compensation to the AGC circuit, as RSSI generated by U301 is lower at cold temperatures compared to normal operation at room temperature. Resistor R300 and capacitor C397 form an R-C network used to dampen any transient instability while the AGC is turning on. 6C-8 5.0 Frequency Generation Circuitry Frequency Generation Circuitry Dual Transistor Voltage Multiplier TRB VCP Aux3 Vmult1 Vmult2 Synthesizer U201 16.8 MHz Ref.

Rx VCO Circuit Aux4 Loop Filter MOD Out Rx Out Matching Network Low Pass Filter Attenuator To PA Driver To Mixer VCOBIC U241 Tx Out Tx VCO Circuit Modulating Signal Figure 6-3: Frequency Generation Unit Block Diagram The Frequency Generation Circuitry is composed of two main ICs, the Fractional-N synthesizer (U201), and the VCO/Buffer IC (U241). Designed in conjunction to maximize compatibility, the two ICs provide many of the functions that normally would require additional circuitry. The synthesizer block diagram illustrates the interconnect and support circuitry used in the region. Refer to the relevant schematics for the reference designators. The synthesizer is powered by regulated 5V and 3.3V which come from U247 and U248 respectively. The synthesizer in turn generates a superfiltered 4.5V which powers U241. In addition to the VCO, the synthesizer must interface with the logic and ASFIC circuitry. Programming for the synthesizer is accomplished through the data , clock and chip select lines from the microprocessor. A 3.3V dc signal from synthesizer lock detect line indicates to the microprocessor that the synthesizer is locked. Transmit modulation from the ASFIC is supplied to pin10 of U201. Internally the audio is digitized by the Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runs through an internal attenuator for modulation balancing purposes before going out to the VCO. Frequency Generation Circuitry 5.1 6C-9 Synthesizer (Refer to UHF Band 2 Synthesizer Schematic Diagram on page 6C-18) The Fractional-N Synthesizer uses a 16.8MHz crystal (FL201) to provide a reference for the system. The LVFractN IC (U201) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as reference frequencies. Together with C206, C207, C208, R204 and CR203 , they build up the reference oscillator which is capable of 2.5ppm stability over temperatures of -30 to 85°C. It also provides 16.8MHz at pin 19 of U201 to be used by ASFIC and LVZIF. The loop filter which consist of C231, C232, C233, R231, R232 and R233 provides the necessary dc steering voltage for the VCO and determines the amount of noise and spur passing through . In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current at pin 45 of U201 to put synthesizer within the lock range. The required frequency is then locked by normal mode charge pump at pin 43 . Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier which is made up of C258, C259, C228, triple diode CR201 and level shifters U210 and U211. Two 3.3V square waves ( 180 deg out of phase) are first shifted to 5V, then along with regulated 5V , put through arrays of diodes and capacitors to build up 13.3V at pin 47 of U201. 8 9 CSX (U409 PIN 2) 10 MOD IN (U404 PIN 40) 13, 30 (U248 PIN 5) 4 LOCK (U409 PIN 56) FREFOUT 19 FREF (U201 PIN 21 & U404 PIN 34) DATA CLOCK (U409 PIN 1) +5V (U247 PIN 4) LOCK 7 DATA (U409 PIN 100) 5, 20, 34, 36 23 REFERENCE OSCILLATOR 24 25 32 47 VOLTAGE MULTIPLIER CLK GND U251 LOW VOLTAGE MODIN FRACTIONAL-N IOUT SYNTHESIZER IADAPT VCC, DC5V MODOUT V , 3.3V 6, 22, 23, 24 CEX DD STEERING LINE 43 45 41 XTAL1 AUX4 3 XTAL2 AUX3 2 WARP SFOUT 2-POLE LOOP FILTER LO RF INJECTION DUAL TRANSIS TORS 28 FILTERED 5V PREIN BIAS1 VCP VMULT2 14 VOLTAGE CONTROLLED OSCILLATOR 40 VMULT1 AUX1 BIAS2 TX RF INJECTION (1ST STAGE OF PA) 39 15 48 DUAL 5V TRANSISTORS R5 PRESCALER IN Figure 6-4 Synthesizer Block Diagram 6C-10 Frequency Generation Circuitry 5.2 VCO - Voltage Controlled Oscillator (Refer to UHF Band 2 Voltage Controlled Oscillator Schematic Diagram on page 6C-19) 5V AUX3 (U201 Pin2) Level Shifter Network AUX4 (U201 Pin3) U201 Pin 32 Prescaler Out TRB_IN Pin 20 Rx-SW Pin7 Tx-SW Pin13 Pin 19 Pin 12 TX/RX/BS Switching Network LO RF INJECTION (U201 Pin28) VSF Steer Line Voltage (VCTRL) Vcc-Superfilter Pin3 Presc Matching Network U241 VCOBIC Low Pass Filter Collector/RF in Pin4 RX RX RX Tank RX VCO Circuit Rx Active Bias Pin5 Pin8 VSF (U201 Pin28) Pin14 Pin6 TX TX Tank TX VCO Circuit Tx Active Bias Pin16 TX Pin10 VCC Buffers TX RF Injection Attenuator Pin15 Vsens Circuit Pin18 Vcc-Logic Pin2 Pin1 Rx-I adjust Tx-I adjust Pins 9,11,17 VSF (U201 Pin28) Figure 6-5 VCO Block Diagram The VCOBIC (U241) in conjunction with the Fractional-N synthesizer (U201) generates RF in both the receive and the transmit modes of operation. The TRB line (U241 pin 19) determines which oscillator and buffer will be enabled. A sample of the RF signal from the enabled oscillator is routed from U241 pin 12, through a low pass filter, to the prescaler input (U201 pin 32). After frequency comparison in the synthesizer, a resultant CONTROL VOLTAGE is received at the VCO. This voltage is a DC voltage between 3.5V and 9.5V when the PLL is locked on frequency. Frequency Generation Circuitry 6C-11 The VCOBIC(U241) is operated at 4.54 V (VSF) and Fractional-N synthesizer (U201) at 3.3V. This difference in operating voltage requires a level shifter consisting of Q260 and Q261 on the TRB line. The operation logic is shown in Table 6-1. Table 6-1: Level Shifter Logic Desired Mode AUX 4 AUX 3 TRB Tx Low High (@3.2V) High (@4.8V) Rx High Low Low Battery Saver Low Low Hi-Z/Float (@2.5V) In the receive mode, U241 pin 19 is low or grounded. This activates the receive VCO by enabling the receive oscillator and the receive buffer of U241. The RF signal at U241 pin 8 is run through a matching network. The resulting RF signal is the LO RF INJECTION and it is applied to the mixer at T302 (refer to UHF Band 2 Receiver Front End Schematic Diagram on page 6C-16). During the transmit condition, when PTT is depressed, five volts is applied to U241 pin 19. This activates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U241. The RF signal at U241 pin 10 is injected into the input of the PA module (U101 pin16). This RF signal is the TX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto the carrier is received through the U201 pin 41. When a high impedance is applied to U241 pin19, the VCO is operating in BATTERY SAVER mode. In this case, both the receive and transmit oscillators as well as the receive transmit and prescaler buffer are turned off. 6C-12 6.0 Notes For All Schematics and Circuit Boards Notes For All Schematics and Circuit Boards * Component is frequency sensitive.

Transmitter 3.0 6D-3 Transmitter P CI C From VCO Antenna Jack Vcontrol Vcontrol PA Driver PA-Final Stage Antenna Switch/ Harmonic Filter/ Matching Network Figure 6-1: Transmitter Block Diagram 3.1 General (Refer to Figure 6-1) The VHF transmitter contains five basic circuits: 1. power amplifier 2. antenna switch 3. harmonic filter 4. antenna matching network 5. power control integrated circuit (PCIC). 3.1.1 Power Amplifier The power amplifier consists of two devices: 1. 9Z67 LDMOS driver IC (U101) and 2. PRF1507 LDMOS PA (Q110). The 9Z67 LDMOS driver IC contains a 2 stage amplification with a supply voltage of 7.3V. This RF power amplifier is capable of supplying an output power of 0.3W (pin 6 and 7) with an input signal of 2mW (3dBm) (pin16). The current drain would typically be 160mA while operating in the frequency range of 330-400MHz. The PRF1507 LDMOS PA is capable of supplying an output power of 7W with an input signal of 0.3W. The current drain would typically be 1300mA while operating in the frequency range of 330400MHz. The power output can be varied by changing the biasing voltage. 6D-4 Transmitter 3.1.2 Antenna Switch The antenna switch circuit consists of two PIN diodes (CR101 and CR102), a pi network (C107, L104 and C106), and two current limiting resistors (R101, R170). In the transmit mode, B+ at PCIC (U102) pin 23 will go low and turn on Q111 where a B+ bias is applied to the antenna switch circuit to bias the diodes "on". The shunt diode (CR102) shorts out the receiver port, and the pi network, which operates as a quarter wave transmission line, transforms the low impedance of the shunt diode to a high impedance at the input of the harmonic filter. In the receive mode, the diodes are both off, and hence, there exists a low attenuation path between the antenna and receiver ports. 3.1.3 Harmonic Filter The harmonic filter consists of C104, L102, C103, L101 and C102. The design of the harmonic filter for VHF is that of a modified Zolotarev design. It has been optimized for efficiency of the power module. This type of filter has the advantage that it can give a greater attenuation in the stop-band for a given ripple level. The harmonic filter insertion loss is typically less than 1.2dB. 3.1.4 Antenna Matching Network A matching network which is made up of L116 is used to match the antenna's impedance to the harmonic filter. This will optimize the performance of the transmitter and receiver into an antenna. 3.1.5 Power Control Integrated Circuit (PCIC) The transmitter uses the Power Control IC (PCIC), U102 to regulate the power output of the radio. The current to the final stage of the power module is supplied through R101, which provides a voltage proportional to the current drain. This voltage is then fedback to the Automatic Level Control (ALC) within the PCIC to regulate the output power of the transmitter. The PCIC has internal digital to analog converters (DACs) which provide the reference voltage of the control loop. The reference voltage level is programmable through the SPI line of the PCIC. There are resistors and integrators within the PCIC, and external capacitors (C133, C134 and C135) in controlling the transmitter rising and falling time. These are necessary in reducing the power splatter into adjacent channels. CR105 and its associated components are part of the temperature cut back circuitry. It senses the printed circuit board temperature around the transmitter circuits and output a DC voltage to the PCIC. If the DC voltage produced exceeds the set threshold in the PCIC, the transmitter output power will be reduced so as to reduce the transmitter temperature. Receiver 4.0 6D-5 Receiver Antenna RF Jack Pin Diode Antenna Switch Varactor Tuned Filter RF Amp Varactor Tuned Filter Mixer Crystal Filter IF Amp AGC Control Voltage from ASFIC First LO from FGU Recovered Audio Squelch Demodulator U301 RSSI IF IC Synthesizer 16.8 MHz Reference Clock SPI Bus Second LO VCO Figure 6-2: VHF Receiver Block Diagram 4.1 Receiver Front-End (Refer to 330-400MHz Receiver Front End Schematic Diagram on page 6D-16 and 330-400MHz Transmitter Schematic Diagram on page 6D-20) The RF signal is received by the antenna and applied to a low-pass filter. For VHF, the filter consists of L101, L102, C102, C103, C104. The filtered RF signal is passed through the antenna switch. The antenna switch circuit consists of two PIN diodes(CR101 and CR102) and a pi network (C106, L104 and C107).The signal is then applied to a varactor tuned bandpass filter. The VHF bandpass filter comprises of L301, L302, C302, C303, C304, CR301 and CR302. The bandpass filter is tuned by applying a control voltage to the varactor diodes(CR301 and CR302) in the filter. The bandpass filter is electronically tuned by the DACRx from U404 which is controlled by the microprocessor. Depending on the carrier frequency, the DACRx will supply the tuned voltage to the varactor diodes in the filter. Wideband operation of the filter is achieved by shifting the bandpass filter across the band. The output of the bandpass filter is coupled to the RF amplifier transistor Q301 via C307. After being amplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned bandpass filter, consisting of L306, L307, C313, C317, CR304 and CR305. Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidth of the filter is about 50 MHz. This enables the filters to be electronically controlled by using a single control voltage which is DACRx . 6D-6 Receiver The output of the post-RF amplifier filter which is connected to the passive double balanced mixer consists of T301, T302 and CR306. Matching of the filter to the mixer is provided by C381. After mixing with the first LO signal from the voltage controlled oscillator (VCO) using low side injection, the RF signal is down-converted to the 45.1 MHz IF signal. The IF signal coming out of the mixer is transfered to the crystal filter (FL301) through a resistor pad and a diplexer (C322 and L310). Matching to the input of the crystal filter is provided by C324 and L311. The crystal filter provides the necessary selectivity and intermodulation protection. 4.2 Receiver Back-End (Refer to 330-400MHz Receiver Back End Schematic Diagram on page 6D-17) The output of crystal filter FL301 is matched to the input of IF amplifier transistor Q302 by components R352 and C325. Voltage supply to the IF amplifier is taken from the receive 5 volts (R5). The IF amplifer provides a gain of about 7dB. The amplified IF signal is then coupled into U301(pin 3) via C330, C338 and L330 which provides the matching for the IF amplifier and U301. The IF signal applied to pin 3 of U301 is amplified, down-converted, filtered, and demodulated, to produce the recovered audio at pin 27 of U301. This IF IC is electronically programmable, and the amount of filtering (which is dependent on the radio channel spacing) is controlled by the microprocessor. Additional filtering, once externally provided by the conventional ceramic filters, is replaced by internal filters in the IF module (U301). The IF IC uses a type of direct conversion process, whereby the externally generated second LO frequency is divided by two in U301 so that it is very close to the first IF frequency. The IF IC (U301) synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LO is designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IF IC. In the absence of an IF signal, the VCO will “search” for a frequency, or its frequency will vary close to twice the IF frequency. When an IF signal is received, the VCO will lock onto the IF signal. The second LO/VCO is a Colpitts oscillator built around transistor Q320. The VCO has a varactor diode, CR310, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filter consisting of C362, C363, C364, R320 and R321. The IF IC (U301) also performs several other functions. It provides a received signal-strength indicator (RSSI) and a squelch output. The RSSI is a dc voltage monitored by the microprocessor, and used as a peak indicator during the bench tuning of the receiver front-end varactor filter. The RSSI voltage is also used to control the automatic gain control (AGC) circuit at the front-end. The demodulated signal on pin 27 of U301 is also used for squelch control. The signal is routed to U404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audio signal is also routed to U404 for processing before going to the audio amplifier for amplification. Receiver 4.3 6D-7 Automatic Gain Control Circuit (Refer to 330-400MHz Receiver Front End Schematic Diagram on page 6D-16) The front end automatic gain control circuit is to provide automatic gain reduction of the front end RF amplifier via feedback. This action is necessary to prevent overloading of backend circuits. This is achieved by drawing some of the output power from the RF amplifier’s output. At high radio frequencies, capacitor C331 provides the low impedance path to ground for this purpose. CR308 is a PIN diode used for switching the path on or off. A certain amount of forward biasing current is needed to turn the PIN diode on. Transistors Q315 provides this current where upon saturation, current will flow via R347, PIN diode, collector and emitter of Q315 and R319 before going to ground. Q315 is an NPN transistor used for switching here. Maximum current flowing through the PIN is mainly limited by the resistor R319. Radio signal strength indicator, RSSI, a voltage signal, is used to drive Q315 to saturation hence turning it on. RSSI is produced by U301 and is proportional to the gain of the RF amplifier and the input RF signal power to the radio. Resistor network at the input to the base of Q315 is scaled to turn on Q315, hence activating the AGC, at certain RSSI levels. In order to turn on Q315, the voltage across the transistor’s base to ground must be greater or equal to the voltage across R319, plus the base-emitter voltage (Vbe) present at Q315. The resistor network with thermistor RT300 is capable of providing temperature compensation to the AGC circuit, as RSSI generated by U301 is lower at cold temperatures compared to normal operation at room temperature. Resistor R300 and capacitor C397 form an R-C network used to dampen any transient instability while the AGC is turning on. 6D-8 5.0 Frequency Generation Circuitry Frequency Generation Circuitry Dual Transistor Voltage Multiplier TRB VCP Aux3 Vmult1 Vmult2 Synthesizer U201 16.8 MHz Ref. Osc. Rx VCO Circuit Aux4 Loop Filter MOD Out Rx Out Matching Network Low Pass Filter Attenuator To PA Driver To Mixer VCOBIC U241 Tx Out Tx VCO Circuit Modulating Signal Figure 6-3: Frequency Generation Unit Block Diagram The Frequency Generation Circuitry is composed of two main ICs, the Fractional-N synthesizer (U201), and the VCO/Buffer IC (U241). Designed in conjunction to maximize compatibility, the two ICs provide many of the functions that normally would require additional circuitry. The synthesizer block diagram illustrates the interconnect and support circuitry used in the region. Refer to the relevant schematics for the reference designators. The synthesizer is powered by regulated 5V and 3.3V which come from U247 and U248 respectively. The synthesizer in turn generates a superfiltered 4.5V which powers U241. In addition to the VCO, the synthesizer must interface with the logic and ASFIC circuitry. Programming for the synthesizer is accomplished through the data , clock and chip select lines from the microprocessor. A 3.3V dc signal from synthesizer lock detect line indicates to the microprocessor that the synthesizer is locked. Transmit modulation from the ASFIC is supplied to pin10 of U201. Internally the audio is digitized by the Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runs through an internal attenuator for modulation balancing purposes before going out to the VCO. Frequency Generation Circuitry 5.1 6D-9 Synthesizer (Refer to 330-400MHz Synthesizer Schematic Diagram on page 6D-18) The Fractional-N Synthesizer uses a 16.8MHz crystal (FL201) to provide a reference for the system. The LVFractN IC (U201) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as reference frequencies. Together with C206, C207, C208, R204 and CR203 , they build up the reference oscillator which is capable of 2.5ppm stability over temperatures of -30 to 85°C. It also provides 16.8MHz at pin 19 of U201 to be used by ASFIC and LVZIF. The loop filter which consist of C231, C232, C233, R231, R232 and R233 provides the necessary dc steering voltage for the VCO and determines the amount of noise and spur passing through . In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current at pin 45 of U201 to put synthesizer within the lock range. The required frequency is then locked by normal mode charge pump at pin 43 . Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier which is made up of C258, C259, C228, triple diode CR201 and level shifters U210 and U211. Two 3.3V square waves ( 180 deg out of phase) are first shifted to 5V, then along with regulated 5V , put through arrays of diodes and capacitors to build up 13.3V at pin 47 of U201. 8 9 CSX (U409 PIN 2) 10 MOD IN (U404 PIN 40) 13, 30 (U248 PIN 5) 4 LOCK (U409 PIN 56) FREFOUT 19 FREF (U201 PIN 21 & U404 PIN 34) DATA CLOCK (U409 PIN 1) +5V (U247 PIN 4) LOCK 7 DATA (U409 PIN 100) 5, 20, 34, 36 23 REFERENCE OSCILLATOR 24 25 32 47 VOLTAGE MULTIPLIER CLK GND U251 LOW VOLTAGE MODIN FRACTIONAL-N IOUT SYNTHESIZER IADAPT VCC, DC5V MODOUT V , 3.3V 6, 22, 23, 24 CEX DD STEERING LINE 43 45 41 XTAL1 AUX4 3 XTAL2 AUX3 2 WARP SFOUT 2-POLE LOOP FILTER LO RF INJECTION DUAL TRANSIS TORS 28 FILTERED 5V PREIN BIAS1 VCP VMULT2 14 VOLTAGE CONTROLLED OSCILLATOR 40 VMULT1 AUX1 BIAS2 TX RF INJECTION (1ST STAGE OF PA) 39 15 48 DUAL 5V TRANSISTORS R5 PRESCALER IN Figure 6-4 Synthesizer Block Diagram 6D-10 Frequency Generation Circuitry 5.2 VCO - Voltage Controlled Oscillator (Refer to 330-400MHz Voltage Controlled Oscillator Schematic Diagram on page 6D-19) 5V AUX3 (U201 Pin2) Level Shifter Network AUX4 (U201 Pin3) U201 Pin 32 Prescaler Out TRB_IN Pin 20 Rx-SW Pin7 Tx-SW Pin13 Pin 19 Pin 12 TX/RX/BS Switching Network LO RF INJECTION (U201 Pin28) VSF Steer Line Voltage (VCTRL) Vcc-Superfilter Pin3 Presc Matching Network U241 VCOBIC Low Pass Filter Collector/RF in Pin4 RX RX RX Tank RX VCO Circuit Rx Active Bias Pin5 Pin8 VSF (U201 Pin28) Pin14 Pin6 TX TX Tank TX VCO Circuit Tx Active Bias Pin16 TX Pin10 VCC Buffers TX RF Injection Attenuator Pin15 Vsens Circuit Pin18 Vcc-Logic Pin2 Pin1 Rx-I adjust Tx-I adjust Pins 9,11,17 VSF (U201 Pin28) Figure 6-5 VCO Block Diagram The VCOBIC (U241) in conjunction with the Fractional-N synthesizer (U201) generates RF in both the receive and the transmit modes of operation. The TRB line (U241 pin 19) determines which oscillator and buffer will be enabled. A sample of the RF signal from the enabled oscillator is routed from U241 pin 12, through a low pass filter, to the prescaler input (U201 pin 32). After frequency comparison in the synthesizer, a resultant CONTROL VOLTAGE is received at the VCO. This voltage is a DC voltage between 3.5V and 9.5V when the PLL is locked on frequency. Frequency Generation Circuitry 6D-11 The VCOBIC(U241) is operated at 4.54 V (VSF) and Fractional-N synthesizer (U201) at 3.3V. This difference in operating voltage requires a level shifter consisting of Q260 and Q261 on the TRB line. The operation logic is shown in Table 6-1. Table 6-1: Level Shifter Logic Desired Mode AUX 4 AUX 3 TRB Tx Low High (@3.2V) High (@4.8V) Rx High Low Low Battery Saver Low Low Hi-Z/Float (@2.5V) In the receive mode, U241 pin 19 is low or grounded. This activates the receive VCO by enabling the receive oscillator and the receive buffer of U241. The RF signal at U241 pin 8 is run through a matching network. The resulting RF signal is the LO RF INJECTION and it is applied to the mixer at T302 (refer to 330-400MHz Receiver Front End Schematic Diagram on page 6D-16). During the transmit condition, when PTT is depressed, five volts is applied to U241 pin 19. This activates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U241. The RF signal at U241 pin 10 is injected into the input of the PA module (U101 pin16). This RF signal is the TX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto the carrier is received through the U201 pin 41. When a high impedance is applied to U241 pin19, the VCO is operating in BATTERY SAVER mode. In this case, both the receive and transmit oscillators as well as the receive transmit and prescaler buffer are turned off. 6D-12 6.0 Notes For All Schematics and Circuit Boards Notes For All Schematics and Circuit Boards * Component is frequency sensitive.

PA driver, U101 and 2. PA final stage, Q100. The LDMOS driver (U101) provides 2-stage amplification using a supply voltage of 7.3V. The amplifier is capable of supplying an output power of 0.3W (pins 6 and 7) with an input signal of 2mW at (pin16). The current drain is typically 120mA while operating in the frequency range of 29.7 - 50 MHz. The power output of this stage is varied by the power control loop which controls the voltage on pin 1. The LDMOS PA is capable of supplying an output power of 8W with an input signal of 0.3W. The current drain is typically 2000 mA while operating in the frequency range of 29.7 - 50 MHz. The final stage gate is bias by a voltage from PCIC pin 24. This voltage is the output of a programmable DAC inside the PCIC and the output is adjustable with the radio tuner. Transmitter 6E-5 3.1.2 Antenna Switch The antenna switch circuit consists of two pin diodes (D100 and D101), a RF network (C147 and L103), and a DC feed network (L104, C144 and current limiting resistor R101). In the transmit mode, PCIC (U102) pin 32 goes high supplying current via the feed network to bias the diodes “on”. The shunt diode (D101) shorts out the receiver port and L103 is connected from the RF path to ground. L103 and the input capacitance of the lowpass filter form a parallel resonant circuit, effectively disconnecting the receiver port from the antenna while not loading the transmit path. In the receive mode, pin 32 goes low and the.the diodes are off. D100 looks like a high impedance disconnecting the transmitter from the antenna while L103 and C147 form a series resonant circuit to connect the receiver to the antenna. 3.1.3 Harmonic Filter The harmonic filter consists of components C103, C106, C107,C110, C111, C114, C115 and 3 inductors which are a part of the SH100 assembly. The harmonic filter for lowband is pole zero design which give greater attenuation lower in frequency where the harmonic energy of the transmitter is the greatest and less attenuation high in frequency where there is less harmonic energy. The harmonic filter insertion loss is typically less than 0.8 dB 3.1.4 Antenna Matching Network The antenna matching network (T100) matches the antenna's impedance with the harmonic filter to optimize the performance of the transmitter and receiver. 3.1.5 Power Control Integrated Circuit (PCIC) The transmitter uses the PCIC (U102) to regulate the power output of the radio. To accomplish this, the voltage across R102 is sensed. This voltage drop is directly proportional to the current drawn in the final stage of the transmitter. This voltage is compared to a programmable reference inside the PCIC and the voltage on PCIC pin 4 adjusted. Pin 4 connects to the PA driver IC (U101) pin 1 via resistor R100 and varies RF output power of the driver. This controls the current drain of the final stage and sets the output power. 3.1.6 Temperature Cut Back Circuit Temperature sensor VR101 and associated components are part of a temperature cut back circuit. This circuit senses the printed circuit board temperature around the transmitter circuits and outputs a DC voltage to the PCIC. If the DC voltage produced exceeds the set threshold of the PCIC, the transmitter output power decreases to reduce the transmitter temperature. 6E-6 4.0 Receiver Receiver Antenna RF Lowpass Jack Filter Antenna Highpass Switch Filter RF Amp Lowpass Filter Mixer Crystal Filter AGC Processing First LO from FGU Recovered Audio Squelch RSSI IF Amp Demodulator IF IC U303 Synthesizer 17.0 MHz Reference Clock SPI Bus Second LO VCO Figure 6-2: Lowband Receiver Block Diagram 4.1 Receiver Front-End The RF signal received by the antenna is routed through the transmitter lowpass filter and antenna switch. These circuits are described in the transmitter section.The signal next passes through a highpass filter consisting of L501, L502, C538, C533 and C504. This filter serves to reject below band signals and has a 3 dB corner frequency of 27 MHz. The output of the highpass filter is connected to an RF amp consisting of Q509 and associated biasing components. This is a BJT amplifier powered off 5 volts and has 13 dB of gain. The amplifier drives a lowpass filter consisting of L503, L504 L507, C534, C535, C536, C537 and C515. This filter is a pole zero design that filters off harmonic components from the RF amp. The 3 dB corner of this filter is at 56 MHz. The output of the lowpass filter is connected to the passive double balanced mixer consisting of components T501, T502, and D501. After mixing with the first local oscillator up-converted to a 109.65 MHz IF signal. The IF signal coming out of the mixer is transferred to the crystal filter (FL301) through a resistor pad (R507, R508 and R509) and a diplexer (C516 and L508). Matching to the input of the crystal filter is provided by L301, L302, C301 and C302. The 3 pole crystal filter provides the necessary selectivity and intermodulation protection. Receiver 4.2 6E-7 Receiver Back-End The output of crystal filter FL301 is connected to the input of IF amplifier transistor U301. Components L303 and C348 and R301 form the termination for the crystal filter and the signal is coupled to one gate of U301 by C303. The IF amplifier is a dual gate MOSFET powered off of the 5 volt supply. The first gate receives the IF signal as indicated previously. The second gate receives a DC voltage from U302 which serves as an AGC control signal. This signal reduces the gain of the IF amplifier to prevent overload of the IF IC, U303. The gain can be varied from a maximum of 13 dB to an attenuation of 55 dB. The output IF signal from U301 is coupled into U303 (pin 3) via C306, R304 and L304 which provides matching for the IF amplifier and U303. The IF signal applied to pin 3 of U303 is amplified, down-converted, filtered, and demodulated, to produce recovered audio at pin 27 of U303. This IF IC is electronically programmable, and the amount of filtering, which is dependent on the radio channel spacing, is controlled by the microprocessor. Additional filtering, once externally provided by the conventional ceramic filters, is replaced by internal filters in IF IC U303. The IF IC uses a type of direct conversion process, whereby the externally generated second LO frequency is divided by two in U303 so that it is very close to the first IF frequency. The IF IC (U303) synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LO is designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IF IC. In the absence of an IF signal, the VCO searches for a frequency, or its frequency will vary close to twice the IF frequency. When an IF signal is received, the VCO locks onto the IF signal. The second LO/VCO is a Colpitts oscillator built around transistor Q301. The VCO has a varactor diode, CR301, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filter consisting of components C308, C309, and R310. The IF IC (U303) also performs several other functions. It provides a received signal-strength indicator (RSSI) and a squelch output. The RSSI voltage is also used to control the automatic gain control (AGC) circuit at the back end. The demodulated signal on pin 27 of U303 is also used for squelch control. The signal is routed to U404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audio signal is also routed to U404 for processing before going to the audio amplifier for amplification. 4.3 Automatic Gain Control Circuit The automatic gain control circuit provides automatic reduction of gain to prevent overloading of backend circuits. This is achieved by lowering the voltage on one gate of U301 which will reduce the drain current in that part and lower its gain. The Radio Signal Strength Indicator (RSS I) voltage signal for the IF IC (U303) is used to drive the AGC processing circuitry consisting of R306, R307, R308, R309 C307 and U302. As the received signal gets stronger, the RSSI line will rise. When the RSSI line passes a certain threshold, the voltage at the output of U302 will begin to drop. This voltage is connected to one gate of IF amplifier U301 through resistor R305. As this voltage decreases, it will lower the drain current in U301 and reduce the gain of the stage. This will limit the power incident on the IF IC, U303. 6E-8 5.0 Frequency Generation Circuitry Frequency Generation Circuitry VSF Voltage Multiplier Switching Network VCP Aux2 Indmult Synthesizer U205 17.0 MHz Ref. Osc. To Mixer Aux3 Loop Filter MOD Out Modulating Signal RX VCO To PA Driver TX VCO Buffer Prescalar input Figure 6-3: Lowband Frequency Generation Unit Block Diagram The frequency generation circuit, shown in Figure 6-3 , is composed of Low Voltage Fractional-N synthesizer U205 and discrete RX VCO, TX VCO.and buffers as well other supporting circuitry. The synthesizer block diagram illustrates the interconnect and support circuitry used in the region. Refer to the schematic for the reference designators. The synthesizer is powered by regulated 5V and 3.3V. The 5 volt signal to the synthesizer as well as the rest of the radio is provided by U204. The 3.3 v signal is provided from U400 in the controller. The 5V signal goes to pins 13 and 30 while the 3.3V signal goes to pins 5, 20, 34 and 36 of U201. The synthesizer in turn generates a superfiltered 4.3V which powers the VCOs and buffers. In addition to the VCO, the synthesizer also interfaces with the logic and ASFIC circuitry. Programming for the synthesizer is accomplished through the data, clock and chip select lines (pins 7, 8 and 9) from the microprocessor, U409. A 3.3V dc signal from pin 4 indicates to the microprocessor that the synthesizer is locked. Transmit modulation from the ASFIC is supplied to pin10 of U205. Internally the audio is digitized by the Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runs through an internal attenuator for modulation balancing purposes before going out at pin 41 to the VCO. Frequency Generation Circuitry 5.1 6E-9 Synthesizer The Fractional-N synthesizer, shown in Figure 6-4, uses a 17.0 MHz crystal (Y201) to provide a reference for the system. Along with being used in the LVFracN, the 17.0 MHz signal is provided at pin 19 of U205 for use by the ASFIC and LVZIF. The LVFractN IC (U205) further divides this by 8 internally to give 2.125 MHz to be used as the reference frequency in the frequency synthesis. While UHF and VHF can use other references, (divide by 7 or divide by 7/8), only the divide by 8 function is valid for lowband. The internal oscillator device in the LVFracN together with C236, C237, C242, R219, CR211and Y201 comprise the reference oscillator. This oscillator is temperature compensated is capable of 2.5 ppm stability over temperatures of -30 to 85°C. There is temperature compensation information that is unique to each crystal contained on Y201 that is programmed into the radio when built. The loop filter consists of components C256, C257, C259, R224, R225 and R228. This circuit provides the necessary dc steering voltage for the VCO and determines the amount of noise and spur passing through. To achieve fast locking for the synthesizer, an internal adapt charge pump provides higher current at pin 45 of U205 to put the synthesizer within lock range. The required frequency is then locked by normal mode charge pump at pin 43. Both the normal and adapt charge pumps get their supply from the inductive voltage multiplier made up of C240, C246, C247, C249, D201, and L223. This circuit provides 13.3V at pin 47 of U205. 8 9 CSX (U409 PIN 2) 10 MOD IN (U404 PIN 40) 13, 30 (U400 PIN 1) 4 LOCK (U409 PIN 56) FREFOUT 19 FREF (U303 PIN 21 & U404 PIN 34) DATA CLOCK (U409 PIN 1) +5V (U204 PIN 4) LOCK 7 DATA (U409 PIN 100) 5, 20, 34, 36 23 REFERENCE OSCILLATOR 24 25 32 47 CLK GND U205 LOW VOLTAGE MODIN FRACTIONAL-N IOUT SYNTHESIZER IADAPT VCC, DC5V MODOUT V , 3.3V CEX DD STEERING LINE 43 45 AUX2 1 XTAL2 AUX3 2 WARP SFOUT 2-POLE LOOP FILTER 41 XTAL1 LO RF INJECTION SWITCHING NETWORK 28 FILTERED 4.3V PREIN VOLTAGE CONTROLLED OSCILLATORS BIAS1 VCP 40 BIAS2 INDMULT VOLTAGE MULTIPLIER 6, 17, 22, 29, 31, 33, 44 39 16 PRESCALER IN Figure 6-4: Lowband Synthesizer Block Diagram TX RF INJECTION (FIRST STAGE OF PA) 6E-10 5.2 Frequency Generation Circuitry VCO - Voltage Controlled Oscillator 5.2.1 Receive VCO The receive VCO is a Colpitts type design and using two active devices in parallel, Q202 and Q204. The oscillator is powered off of the 4.3 volt super filter supply when the AUX3 line goes low. The oscillator operates from 139 to 160 MHz, and the frequency is tuned by varactor diodes CR201 and CR202. 5.2.2 Transmit VCO The transmit VCO is a Hartley type design with active devices Q203. The oscillator is powered off of the 4.3 volt super filter supply when the AUX2 line goes low. The oscillator operates from 29.7 to 42 MHz for Range 1 and 35 to 50 MHz for Range 2. The frequency is tuned by varactor diodes in U203. Note that the values of the inductive tap, L208 and L209, and the capacitor C215 which couples the varactor to the oscillator tank vary between the ranges. 5.2.3 Buffer Both the receive and transmit VCO are fed to a buffer amplifier Q201. This is a BJT amplifier that boosts the signal levels to +4 dBm and provides reverse isolation to the oscillators. The amplifier is powered off the 4.3 volt super filter supply and the feed network is combined with the transmit filter. 5.2.4 Diplexer and Output Filters The output of the buffer drives a pair of parallel filters. One filter is a lowpass filter in the TX pass that passes 29.7 - 50 MHz signals for the transmitter into the power amplifier while rejecting the receive LO injection signals at 139 - 160 MHz. This filter is comprised of L204, L211, L212, C230 and C231. The other filter is a highpass filter which passes 139 - 160 MHz signals for the receive LO into the mixer while rejecting the transmit injection signals at 29.7 -50 MHz. This filter is comprised of C228,C229,C235 and L215. 5.2.5 Prescalar Feedback The prescalar input signal for receive and transmit is tapped off of the outputs of each filter by resistors R234 and R238. This signal is routed to U205 pin 32. After frequency comparison in the synthesizer, current is transferred in the loop filter and a control voltage is generated at the output of the loop filter to adjust the frequency of the VCO. This voltage is a DC voltage between 3.5V and 9.5V when the PLL is locked on frequency.
