Qualification Testing: SMI can perform most of these tests in-house and will coordinate with outside labs for those other tests, such as shock and vibration that require special equipment. SMI will design and build the necessary tools to facilitate these tests. Connector type Freq are ideal in military and space flight applications where power management and low loss interconnects are critical. 2.92 mm 40 GHz SMI connectors have the lowest VSWR in 2.40 mm 50 GHz the industry, with typical VSWR of 1.10 : 1 TNC 18 GHz (return loss of -26 dB) up to 50 GHz. N 18 GHz SSMA 36 GHz SMI offers the additional advantage Installation and Tools 27 GHz Super SMA TM Launch Accessories Southwest Microwave connectors Cable Connectors Source Inspections: SMI has hosted many source inspections in coordination with several major space and hi-rel customers, and is familiar with what is required to facilitate and streamline them. Adapters Source Control Drawings (SCD): SMI has an extensive database of customer source control drawings for commercial and hi-rel applications. Due to extensive experience working with SCD’s, SMI is frequently asked to contribute technical material and assistance in their creation. Destructive Physical Analysis (DPA): When DPA is required, SMI works with several quality labs that provide DPA services. SMI oversees the testing and integrates the DPA results into the ATR. End Launch Connectors Material Traceability: All material used in connector assemblies has traceability to raw material. This allows SMI to use any item in stock for space level applications. 2.40 mm Connectors Outgassing: All material used in connector assemblies meet NASA outgassing requirements. (See page 97) Space Screening: Test plans are generated in accordance with SCD requirements and most tests are performed in-house. Tests are performed and the results recorded in accordance with the test plan. The results are then combined with material certs and lot traceability information into a document called an Acceptance Test Report (ATR). 2.92 mm Connectors COTS Considerations SSMA Connectors Southwest Microwave uses MIL-PRF-39012 as a reference for interface specifications and test methods. There are additional tests SMI recommends be performed in addition to MIL-PRF-39012 to ensure proper performance during the actual usage of the connectors. The most important of these is thermal shock to ensure the interface and the electrical performance are stable over the full temperature range. MIL-PRF-39012 does not require testing after temperature cycling. of low RF leakage of <-100 dB typical.

When the contact resistance approaches surface resistance including skin effect, the ultimate power handling level will be approached. Application results are affected by heat-sinking of the connector plus the connector’s construction and use of highertemperature materials. Another limiting factor is altitude because of the connector's increasing inability to dissipate heat as altitude increases. Power derating factors for temperature and altitude are provided on the following table. Thus, there is not an absolute power handling figure for a connector type. Results may vary from supplier-to-supplier due to design, materials and manufacturing latitudes taken by each. Therefore published power ratings are typically conservative. Installation and Tools Launch Accessories Cable Connectors End Launch Connectors The following graph summarizes industry acceptable average power rating for a variety of coaxial connector types. The key characteristic that determines average power handling capabilities for mated coaxial connectors is its ability to pass high current and keep heat-rise to a moderate temperature. This heating directly relates to contact resistance. Contact resistance is a function of contact surface area. Therefore properly formed center contacts are critical. If connectors are long, then conductor length resistance may start to dominate. The average power rating decreases with frequency because the resistive losses increase with frequency. Adapters 2.40 mm Connectors 2.92 mm Connectors SSMA Connectors TNC Connectors N Series Connectors Appendix Power Rating for Coaxial Connectors 98 Extended Power Super SMA Southwest Microwave’s “Extended Power Super SMA” connectors provide additional power handling capabilities above most standard SMA connectors because they operate reliably at higher temperatures (165°C) with moderate power (160W) or at higher / extended power (250W) at 125°C. The temperature rating as specified is the temperature that the connector will withstand and still meet the electrical specifications. As a basic guideline, the Extended Power Super SMA will handle an additional 100W average power above what is represented in the following power chart for SMA. Therefore the recommended maximum power rating for Extended Power Super SMA connector is 250W CW at Ku-band (12.4–18.0 GHz), at a maximum temperature of 125°C.

Cable Connectors When the proper procedure for mating microwave connectors is followed, no rotational torque is applied to the center conductors. If the body of either connector is rotated, this is improper and can apply a rotational torque to the center conductor. All Southwest Microwave connectors have the center conductor rigidly captured to the outer housing. The center conductor captivation is, in most cases, accomplished with a high temperature plastic bead. This bead provides high axial retention at extended temperatures, but does not provide for any rotational resistance. Therefore proper mating is strongly recommended. Adapters 4.
