M3933/25-90S

Overview

The M3933/25-90S is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a nominal attenuation of 30 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.

Feature Summary

• Compliant with MIL-DTL-M3933 specifications for military-grade reliability
• Fixed attenuation design ensures stable signal reduction without adjustment
• Robust construction suitable for demanding environmental conditions

Applications

• Military communication systems requiring precise signal attenuation
• Test and measurement equipment operating up to 18 GHz
• RF circuit protection and signal level control in defense applications

Procurement Notes

Verify the specific suffix 'S' against official datasheets to confirm connector gender and screening requirements. Confirm compliance with MIL-DTL-M3933 standards. Check RoHS status as these components may not be compliant. Validate lead times due to potential manufacturing delays.

Selection Notes

Select this model when a fixed 30 dB attenuation is required at frequencies up to 18 GHz. Ensure the SMA interface matches system connectivity needs. Consider the 2W power handling capability relative to system signals. Verify temperature ratings align with operational environments.

Part Context
