M3933/16-28S

Overview

The M3933/16-28S is a screened RF attenuator manufactured by Amphenol SV Microwave, designed for military specifications. It features SMA connectors with a female-to-male configuration and operates within a frequency range of 0 Hz to 18 GHz. The component provides a fixed attenuation value of 11 dB at a characteristic impedance of 50 Ohms. It supports a maximum 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 signal integrity in demanding environments
• Fixed 11 dB attenuation for precise signal level control
• Military specification compliance for rugged operational reliability

Applications

• Military radar systems requiring stable signal attenuation
• Avionics communication equipment operating at high frequencies
• Test and measurement instrumentation for RF calibration

Procurement Notes

Verify the specific screening status and connector gender configuration against project requirements before procurement. Confirm that the 11 dB attenuation value aligns with system design needs. Ensure environmental ratings meet the operational temperature extremes of the intended application. Cross-reference the MIL-spec designation with official manufacturer documentation to confirm authenticity and performance characteristics.

Selection Notes

Select this component when a fixed 11 dB attenuation is required within the 18 GHz bandwidth. The screened design is suitable for applications needing reduced electromagnetic interference. Verify compatibility with existing SMA interfaces and ensure the 2 W power handling capacity exceeds peak signal levels. Consider the wide temperature range for deployment in harsh or aerospace environments.

Part Context

This part belongs to the M3933 series of RF attenuators from Amphenol SV Microwave, which are built to meet rigorous military standards. The series includes various attenuation values and connector configurations, all sharing common electrical and mechanical robustness traits suitable for defense and aerospace sectors.

Replacement Considerations

Direct substitutes include other M3933/16-series attenuators with identical 11 dB attenuation and screened construction. Verify that any replacement maintains the same SMA female-to-male interface and 50 Ohm impedance to ensure mechanical and electrical compatibility without circuit modification.
