M3933/25-65S

Overview

The M3933/25-65S is a screened SMA male-to-female RF attenuator manufactured by Amphenol SV Microwave. It operates within an 18 GHz frequency range with a nominal attenuation of 3.5 dB and a 50 Ohm impedance. The component supports a maximum power rating of 2 W and functions between -55°C and +125°C.

Feature Summary

• Screened construction for enhanced environmental protection
• SMA gender configuration for standard interconnect compatibility
• Designed for high-frequency signal attenuation applications

Applications

• Military radio systems
• Avionics test equipment
• Satellite communication links

Procurement Notes

Verify the specific suffix 'S' denotes screened variants when sourcing. Confirm that the 3.5 dB attenuation value matches system requirements. Ensure the SMA male-to-female orientation aligns with the intended circuit topology before finalizing procurement orders.

Selection Notes

Select this model for applications requiring precise 3.5 dB signal reduction in the 18 GHz band. The screened design offers superior shielding compared to non-screened counterparts. Verify thermal management capabilities given the 2 W power rating and operating temperature limits.

Part Context

This part belongs to the M3933 series of RF military specification connectors. It serves as a specialized attenuator variant within the broader SMA connector family, providing controlled signal loss rather than simple connectivity.

Replacement Considerations

M3933/25-65N is the non-screened parameter equivalent from the same manufacturer.
