M3933/25-24N

Overview

The M3933/25-24N is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a nominal attenuation of 24dB with a 50 Ohm impedance. The device operates within a frequency range of 0 Hz to 2 GHz and supports a power rating of 2W. It utilizes SMA connectors in an in-line module configuration.

Feature Summary

• Complies with MIL-DTL-M3933 military specifications for high reliability
• Features SMA single-row module connector interface
• Designed for operation in harsh environments

Applications

• Military communication systems
• Aerospace instrumentation
• Test and measurement equipment

Procurement Notes

Verify the specific suffix (N or S) against the procurement requirement, as it denotes connector gender. Confirm that the 2 GHz frequency limit meets system requirements, as other models in this series support higher frequencies up to 18 GHz. Ensure compliance with non-RoHS status if environmental regulations apply to the final assembly.

Selection Notes

Select this model when a precise 24dB attenuation is required at lower microwave frequencies. Compare against the M3933/25-50N if the application requires operation beyond 2 GHz, as that variant supports up to 12.4 GHz. Verify power handling needs against the 2W rating before integration into high-power signal chains.
