M3933/25-71N

Overview

The M3933/25-71N is a fixed RF attenuator manufactured by Amphenol SV Microwave, designed for military specifications. It utilizes SMA connectors with a male-to-female configuration and operates within a frequency range of DC to 18 GHz. The component provides a nominal attenuation value of 6.5 dB at a characteristic impedance of 50 Ohms. It supports a maximum power rating of 2 Watts and functions reliably across an operating temperature range from -65°C to +165°C.

Feature Summary

• Military-grade construction compliant with MIL-Spec standards
• SMA connector interface for secure high-frequency connections
• Fixed attenuation design for precise signal level control

Applications

• Satellite microwave circuit power level adjustment
• RF test and measurement instrumentation
• Defense communication systems requiring screened components

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm screening status and exact electrical tolerances. Ensure compatibility with system impedance requirements before integration. Confirm that the screened variant meets all necessary environmental and reliability standards for the intended operational environment.

Selection Notes

Select this model when a fixed 6.5 dB attenuation is required in the 18 GHz band. Consider the SMA interface for standard connectivity needs. Evaluate the 2W power handling capability against system peak power levels. Ensure the wide temperature range suits the deployment conditions.

Part Context
