2. SGH-Z500 Circuit Description
1. SGH-Z500 RF Circuit Description
1. Antenna Switch Module (U101)
The antenna switch module allows multiple operating bands and modes to share the same antenna. A common
antenna connects to one of five paths: 1) UMTS-2100 Rx/Tx, 2) EGSM-900 Rx, 3) EGSM-900 Tx, 4) DCS-1800
Rx, and 5) DCS-1800 Tx. 6) PCS-1900 Tx, 7) PCS-1900 Rx, UMTS operation requires simultaneous reception
and transmission.
2. Filter
To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band.
- GSM Rx FILTER (F101) → For filtering the frequency band between 925 ~ 960 MHz.
- DCS Rx FILTER (U103) → For filtering the frequency band 1805 and 1880 MHz.
- DCS Rx FILTER (F102) → For filtering the frequency band 1930 and 1990 MHz.
- WCDMA Rx FILTER (F201) → For filtering the frequency band 2110 and 2170 MHz.
- WCDMA Tx FILTER (F202) → For filtering the frequency band 1920 and 1980 MHz.
3. VCTCXO (OSC201)
To generate the 19.2MHz reference clock to drive the logic and RF.
4. Duplexer (F203)
A duplexer splits a single operating band into receive and transmit paths.
5. UMTS PAM (U201)
This is a key component in the transmitter chain and must complement the RTR6250 IC precisely; jointly they
dominate the UMTS transmitter performance characteristics. Parameters such as gain, output power level, ACLR,
harmonics, Rx-band noise, and power supply current are critical.
6. GSM/DCS/PCS PAM (U105)
The PAM is a key component in any transmitter chain and must complement the rest of the transmitter precisely.
For GSM,DCS,PCS operation, the closed-loop transmit power control functions add even more requirements
relative to the UMTS PA. In addition to gain control and switching requirements, the usual RF parameters such
as gain, output power level, several output spectrum requirements, and power supply current are critical.
7. GSM/DCS/PCS l Tx VCO (U104)
The Tx VCO outputs for EGSM, DCS, PCS drive a resistive network that splits the active signal into two signals:
1) the input to the active PAM ? this is the low loss path, and 2) the OPLL feedback signal.
8. RF VCO (OSC202)
The single-band UHF VCO is a key component within its phase-locked loop; VCO performance directly impacts
PLL and transceiver performance. UMTS Rx LO signal is generated from this
VCO's output.
2-1
Circuit Description
9. RFL6200 (U202)
The RFL6200 includes an LNA circuit optimized for UMTS-2100 operation. The LNA is separated from all other
receive functions contained within the RFR6200 receiver IC to improve mixer LO to RF isolation ? a critical
parameter in the Zero-IF architecture.
10. RFR6200 (U203)
The RFR6200 provides the Zero-IF receiver signal path, from RF to analog baseband, for UMTS-2100
applications. The RFR6200 accepts its UMTS input signal from the handset RF front-end design. The UMTS input
is configured differentially to optimize second-order inter-modulation and common mode rejection performance, and
implements MSM-controlled gain adjustments to extend the receiver dynamic range.
11. RTR6250 (U102)
The RTR6250 supports multi-band, multi-mode phones with two receiver signal paths and three transmitter signal
paths:
1) Receiver paths
- EGSM-900
- DCS-1800
- PCS-1900
2) Transmitter paths
- EGSM-900 (using OPLL technique)
- DCS-1800 (using OPLL technique)
- PCS-1900
- UMTS-2100
Numerous secondary functions are integrated on-chip as well:

1. PM6650
1.1. Power Management
Ten low-dropout regulators designed specifically for GSM applications power the terminal and help ensure optimal
system performance and long battery life. It provides LDOs support for 1.375V, 1.8V, 2.6V, 2.85V,
3.3V.
IC-level interfaces include the three-line serial bus interface(SBI) used by the MSM6250 device to control
and status the PM6650 IC.
1.2. Keypad Backlight
The Keypad backlight driver output is at pin 23 (KYPD_BACKLIGHT_DRV) and is designed to drive parallel
connected LEDs directly. Its output current level is SBI-programmable and meets the performance specified below.
Input parameters are not specified since they are internal.
1.3. TCXO Controller and Buffers
The PM6650 IC includes circuits for controlling the TCXO warm-up and buffering its signal for distribution
throughout the handset. Performance specifications are presented below.
2. Connector
2-1. LCD Connector
LCD is consisted of main LCD(color 262K TFT LCD) and small LCD(OLED color 65K LCD). Chip select signals
in the U302, MAIN_LCD_CS can enable main LCD and SUB_LCD_CS can enable small LCD. CAM_PWR_ON
signal enables white LED of main LCD. MAIN_LCD_RESET signal initiates the reset
process of the main LCD. SUB_LCD_RESET signal initiates the Reset process of the small LCD.
16-bit data lines(D2(0)~D(15)) transfers data and commands to LCD. Data and commands use "RS" signal.
If this signal is high, Inputs to LCD are commands. If it is low, Inputs to LCD are data. The signal which informs
the input or output state to LCD, is required. But this system is not necessary this signal.
Power signals for LCD are "VBATT_LCD". "SPKP_RCVP" and "SPKP_RCVN" from U603 are used for audio
speaker. And "MOTOR_EN" from U302 enables the motor.
2-2. Key
This is consisted of key interface pins among U302, KEYSENSE_N(0:4). These signals compose the matrix.
Result of matrix informs the key status to key interface in the U302. Power on/off key is seperated from the
matrix. The key LED use the "VBATT" supply voltage.
"KEY_LED" signal enables LEDs with current control.
"HALL_SW" informs the status of folder (open or closed) to the. This uses the hall effect IC, A3212ELH.

YMU765 has a built-in amplifier, and thus, is an ideal device for outputting sounds that are used by mobile
phones in addition to game sounds and ringing melodies that are replayed by a synthesizer.
The synthesizer section adopts "stereophonic hybrid synthesizer system" that are given advantages of both FM
synthesizers and Wave Table synthesizers to allow simultaneous generation of up to 32 FM voices and 32 Wave
Table voices. Furthermore, YMU765 has a built-in hardware sequencer that helps to realize complex play without
heavily loading the host CPU. And this device also has a built-in circuit for controlling vibrators and LEDs
synchronizing with play of music. The consumed electric current can be stopped to the minimum by power down
mode when not operating.
The hardware sequence built in this device allows playing of the complex music without giving excessive load to
the CPU of the portable telephones. Moreover, the registers of the FM synthesizer can be operated directly for
real time sound generation, allowing, for example, utilization of various sound effects when using the game
software installed in the portable telephone.
