Procurement Notes

Verify the specific datasheet version for the M3933/16-31N to confirm exact mechanical dimensions and mating interface details. Ensure that the procurement channel sources genuine Amphenol SV Microwave components to guarantee compliance with military specification standards. Cross-reference the part number against official manufacturer catalogs to avoid substitution errors during integration.

Selection Notes

Select this model when a fixed 12.5 dB attenuation is required at frequencies up to 18 GHz. Consider the SMA connector type for compatibility with existing test fixtures. Evaluate the 2 W power rating against system peak power requirements. Verify that the extended temperature range meets the environmental conditions of the intended deployment scenario.

Part Context

This component belongs to the M3933 series of connectorized attenuators from Amphenol SV Microwave. The series offers various attenuation values within the SMA format. The M3933/16-31N specifically addresses needs for moderate signal reduction in high-frequency circuits. It complements other models in the family that offer different attenuation levels or screened variants.

Replacement Considerations

Check for direct substitutes within the M3933/16 series offering identical 12.5 dB attenuation. Verify compatibility with SMA connectors if replacing with generic equivalents. Ensure any alternative maintains the 18 GHz frequency limit and 2 W power rating.
