M3933/25-79N

Overview

The M3933/25-79N is a screened RF attenuator manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It provides an attenuation value of 11 dB with a frequency range spanning from 0 Hz to 18 GHz. The component features SMA connectors and operates at a maximum power dissipation of 2 Watts. Designed for high reliability, it adheres to military specifications and includes screening requirements.

Feature Summary

• Provides precise 11 dB signal attenuation across a wide DC to 18 GHz bandwidth
• Constructed as a coaxial inline module with SMA connectors
• Screened to meet specific military quality and performance standards

Applications

• Military communication systems requiring screened components
• Test and measurement equipment operating up to 18 GHz
• High-frequency signal conditioning in defense electronics

Procurement Notes

Verify current availability and lead times directly with the manufacturer or authorized distributors, as this item may be subject to special ordering processes. Confirm that the required screening level matches your specific project documentation. Ensure compatibility with existing SMA interfaces and verify that the 2W power rating meets system thermal requirements before finalizing procurement.

Selection Notes

Select this component when a fixed 11 dB attenuation is required within a 0 Hz to 18 GHz operational range. The SMA connector type dictates interface compatibility. Consider the 2W power handling capability relative to system signal levels. The screened version is necessary for applications demanding verified military-grade quality assurance and traceability.

Part Context

This part belongs to the M3933/25 series of screened RF attenuators. It shares the same form factor and general specifications as other values in the series, such as the 75N variant which offers 8.5 dB attenuation. The series is characterized by its robust construction and suitability for harsh environments typical of defense and aerospace applications.

Replacement Considerations

Direct substitutes include other M3933/25 series variants with different attenuation values, such as M3933/25-75N (8.5 dB) or M3933/25-79S (11 dB screened). Verify that any replacement maintains the required screening status and SMA connector gender/configuration.
