• Military RF system signal conditioning
• High-frequency test and measurement equipment

Procurement Notes

Verify the specific datasheet for the M3933/16-42N to confirm exact mechanical dimensions and mating connector gender details. Ensure compatibility with existing SMA interface requirements in the target assembly. Cross-reference official manufacturer documentation for precise thermal and electrical limits before integration.

Selection Notes

Select this component when a fixed 18 dB reduction is required in 50-ohm systems operating up to 18 GHz. Consider the stainless steel build for harsh environments requiring extended temperature tolerance. Verify that the SMA plug-to-jack orientation matches the system interconnect needs.

Part Context

This part belongs to the M3933 series of RF fixed attenuators from Amphenol SV Microwave. These components are engineered for military-grade reliability and typically utilize SMA connectors. The series offers various attenuation values and frequency ranges to suit diverse RF application requirements.

Replacement Considerations

Check for direct cross-references or equivalent MIL-spec attenuators with identical 18 dB attenuation and SMA interfaces. Ensure substitute parts match the 50-ohm impedance and 18 GHz frequency limit.
