M3933/16-56N

Overview

The M3933/16-56N is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a nominal attenuation of 28 dB with a frequency range extending from 0 Hz to 18 GHz. The component operates at a maximum power rating of 2 W and utilizes SMA connectors in an inline module configuration. Designed for military applications, it complies with MIL-DTL-M3933 standards.

Feature Summary

• Complies with MIL-DTL-M3933 military specifications for qualified product list (QPL) components.
• Provides precise 28 dB signal attenuation across a wide DC to 18 GHz bandwidth.
• Features robust SMA connector interface suitable for high-frequency RF environments.

Applications

• Military radar systems requiring precise signal level control
• Test and measurement equipment operating up to 18 GHz
• Communication subsystems needing fixed attenuation stages

Procurement Notes

Verify the specific suffix designation against the manufacturer's current QPL documentation to ensure compliance with the latest MIL-DTL-M3933 requirements. Confirm that the SMA connector gender and mating interface match the system design constraints. Check for RoHS status as these military-grade components may not meet standard environmental directives. Ensure storage conditions align with the specified moisture sensitivity level to maintain performance integrity prior to installation.

Selection Notes

Select this model when a fixed 28 dB attenuation value is required within the 0 Hz to 18 GHz operational band. The 2 W power rating supports moderate signal levels typical in many RF front-end architectures. Consider the SMA interface compatibility with existing PCB or cable assemblies. Evaluate thermal management needs based on the continuous wave power dissipation capabilities defined in the official datasheet for the specific ambient temperature conditions.

Part Context

This part belongs to the M3933/16 series of fixed attenuators produced by Midwest Microwave, a division of Cinch Connectivity Solutions. These components are engineered for high-reliability applications where strict adherence to military standards is mandatory. The series offers various attenuation values and frequency ranges, with the M3933/16-56N specifically addressing the need for higher attenuation at microwave frequencies.

Replacement Considerations

Direct substitutes include other M3933/16 series variants with identical electrical parameters but different attenuation values, such as M3933/16-13S or M3933/16-22S, if the system allows for adjustment. Cross-brand replacements must match the 28 dB attenuation, 18 GHz frequency limit, 2 W power rating, and SMA connector type while maintaining MIL-DTL-M3933 compliance.
