M3933/16-50S

Overview

The M3933/16-50S is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a nominal attenuation of 22.5 dB with a 50 Ohm impedance. The device operates within a frequency range of 0 Hz to 18 GHz and supports a power rating of 2 Watts. It utilizes SMA connectors in an in-line module configuration. The component complies with MIL-DTL-M3933 standards and is designated as a Qualified Products List (QPL) item.

Feature Summary

• Compliance with MIL-DTL-M3933 military specifications for qualified products
• Fixed attenuation value of 22.5 dB for precise signal control
• Broadband operation capability extending up to 18 GHz
• Robust SMA connector interface for secure in-line integration

Applications

• Military electronic systems requiring certified RF components
• Aerospace communication equipment testing and signal conditioning
• High-frequency test and measurement instrumentation setups
• Defense radar system signal path management

Procurement Notes

Verify that the specific part number matches the required 22.5 dB attenuation value, as this series includes various attenuation steps. Confirm compliance with MIL-DTL-M3933 requirements if military qualification is mandatory for the application. Ensure SMA connector gender compatibility with existing cable assemblies. Check for any specific screening or inspection reports required by the end-user specification before final acceptance.

Selection Notes

Select this model when a fixed 22.5 dB reduction is needed within an 18 GHz bandwidth. The 2W power rating suits moderate power levels common in many RF chains. The SMA interface offers widespread compatibility. Consider the in-line module form factor for easy insertion into existing coaxial lines. Verify that the 50 Ohm impedance matches the system design to prevent signal reflections.

Part Context

This component belongs to the M3933/16 series of fixed attenuators from Midwest Microwave. These parts are designed for high-reliability applications under strict military standards. The series offers various attenuation values while maintaining consistent electrical performance across the specified frequency range. The QPL status indicates adherence to rigorous manufacturing and quality control protocols defined by defense specifications.

Replacement Considerations

Direct substitutes include other M3933/16 series variants with different attenuation values if the 22.5 dB requirement changes. Equivalent commercial parts must match the 18 GHz frequency limit, 2W power rating, and SMA interface. Verify that any replacement also meets MIL-DTL-M3933 standards if military qualification is required.
