M3933/25-35N

Overview

The M3933/25-35N is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a nominal attenuation value of 9dB with a system impedance of 50 Ohms. The component utilizes SMA connectors and operates within a frequency range from DC to 18 GHz. It is designed for high-power applications with a power rating of 2W. The unit complies with MIL-DTL-M3933 standards, ensuring suitability for military-grade environments.

Feature Summary

• Complies with MIL-DTL-M3933 specifications for military-grade reliability
• Features SMA coaxial connectors for secure interconnection
• Supports high-power operation with a 2W rating
• Provides fixed 9dB attenuation across a wide frequency bandwidth

Applications

• Military communication systems requiring precise signal reduction
• Aerospace test and measurement instrumentation
• High-frequency RF circuit protection and level adjustment
• Defense electronics signal conditioning modules

Procurement Notes

Verify the specific suffix (N or S) matches the required connector gender configuration, as this determines male or female interface compatibility. Confirm that the 18 GHz maximum frequency aligns with the application's operational bandwidth requirements. Ensure compliance with MIL-DTL-M3933 standards is necessary for the intended deployment environment. Check RoHS status if environmental regulations apply to the final assembly.

Selection Notes

Select this model when a fixed 9dB attenuation is required at frequencies up to 18 GHz. The SMA interface suits standard coaxial testing setups. Consider the 2W power handling capability for high-signal environments. Verify impedance matching to 50 Ohms systems to prevent signal reflection. Compare against other M3933/25 variants for different attenuation values or frequency limits.

Part Context

This component belongs to the M3933/25 series of connectorized attenuators produced by Midwest Microwave, a brand under Cinch Connectivity Solutions. The series offers various fixed attenuation values within a ruggedized form factor.
