M3933/16-22S

Overview

The M3933/16-22S is a screened RF attenuator manufactured by Amphenol SV Microwave, designed for military specifications. It features SMA male-to-female connectors and operates within a frequency range of 0 Hz to 18 GHz. The component maintains a 50 Ohm impedance and provides a maximum attenuation of 5.5 dB. It supports a power rating of 2 W and functions reliably across an operating temperature range from -65°C to +165°C.

Feature Summary

• Screened construction for enhanced environmental protection in military applications
• SMA connector interface ensuring compatibility with standard RF systems
• Wide operational temperature tolerance suitable for extreme conditions

Applications

• Military radio communication systems
• Avionics signal conditioning
• Test and measurement equipment requiring precise attenuation

Procurement Notes

Verify the specific screening requirements against mission parameters before procurement. Confirm that the SMA gender configuration matches the system interconnect needs. Ensure thermal management strategies align with the specified operating temperature limits. Validate impedance matching to prevent signal reflection issues in high-frequency deployments.

Selection Notes

Select this model when a fixed 5.5 dB attenuation is required at frequencies up to 18 GHz. Consider the screened variant for environments demanding higher electromagnetic interference protection. Evaluate the 2 W power handling capability against peak signal levels. Compare against other MIL-spec attenuators if different connector types or attenuation values are necessary.

Part Context

This part belongs to the M3933 series of RF attenuators, which are engineered for rugged defense and aerospace applications. The series utilizes robust SMA interfaces to maintain signal integrity under vibration and shock. Amphenol SV Microwave designs these components to meet stringent military standards for reliability and performance consistency.

Replacement Considerations

M3933/16-05S offers 1 dB attenuation. M3933/16-09S provides 7 dB attenuation. M3933/25-31S features reversed SMA gender orientation with 5 dB attenuation.
