Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm exact screening levels and connector gender configurations. Ensure that the procurement specifications align with the required military standards and environmental ratings defined in the datasheet before finalizing orders.

Selection Notes

Select this component when a fixed 13 dB attenuation is required at frequencies up to 18 GHz. Consider the SMA interface compatibility and the 2 W power handling capability. Evaluate the wide operating temperature range suitability for the intended deployment environment compared to commercial-grade alternatives.

Part Context

This model belongs to the M3933 series of RF attenuators produced by Amphenol SV Microwave. The series includes various attenuation values and connector types tailored for MIL-Spec applications. This specific variant focuses on the 13 dB attenuation value within the SMA connector family.

Replacement Considerations

Cross-reference with other M3933/16 variants for different attenuation values. Verify mechanical dimensions and mating connector genders against existing system requirements to ensure direct interchangeability without adapter usage.
