M3933/25-69S

Overview

The M3933/25-69S is a screened RF attenuator manufactured by Amphenol SV Microwave, conforming to MIL-DTL-39017 specifications. It features SMA connectors with a male plug on one side and a female jack on the other. The component operates within a frequency range up to 18 GHz and maintains a characteristic impedance of 50 Ohms. It provides a fixed attenuation value of 5.5 dB. The unit is rated for a maximum power handling capacity of 2 W and functions reliably across an operating temperature range from -65 °C to +165 °C.

Feature Summary

• Screened construction designed to minimize electromagnetic interference in sensitive environments
• Military-grade reliability compliant with MIL-DTL-39017 standards
• High-temperature stability suitable for extreme operational conditions

Applications

• Military radar systems requiring precise signal level control
• Avionics test and measurement equipment
• Satellite communication ground stations

Procurement Notes

Verify the specific suffix 'S' indicates screened construction when ordering. Confirm that the military specification requirements align with project needs. Ensure compatibility with SMA mating interfaces. Check for updated datasheets regarding environmental testing results. Validate supplier authorization for defense-grade components.

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 applications demanding superior shielding performance compared to standard versions. Evaluate the 2 W power rating against peak signal levels. Assess the wide temperature range suitability for harsh environment deployments.
