M3933/25-36S

Overview

The M3933/25-36S is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a nominal attenuation of 10dB with a characteristic impedance of 50 Ohms. The device operates within a frequency range of 0 Hz to 12.4 GHz and supports a maximum power rating of 2W. It utilizes SMA single-row module connectors for interface. The component is classified as a military-grade part compliant with MIL-DTL-M3933 standards, though it does not meet RoHS specifications.

Feature Summary

• Provides precise 10dB signal attenuation for RF applications
• Operates across a wide bandwidth from DC to 12.4 GHz
• Features robust SMA connectorized construction for reliable interconnection
• Complies with MIL-DTL-M3933 military qualification standards

Applications

• Military communication systems requiring signal level control
• Aerospace test and measurement instrumentation
• Defense electronic warfare equipment
• High-frequency RF circuit calibration setups

Procurement Notes

Verify that the specific order suffix 'S' corresponds to the SMA connector configuration required for your system integration. Confirm that the non-RoHS status aligns with your facility's environmental compliance regulations. Ensure that the 2W power handling capacity meets the peak and average power requirements of your RF chain. Check for any specific screening or QPL documentation requirements mandated by your defense contracts.

Selection Notes

Select this model when a fixed 10dB attenuation value is necessary within the 12.4 GHz frequency limit. The SMA interface must match the existing connector type in the signal path. Consider the 50 Ohm impedance matching to prevent signal reflection. Evaluate the 2W power rating against potential thermal dissipation constraints in the installation environment.

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 attenuation values while maintaining consistent electrical performance and mechanical form factors suitable for rugged environments. These parts are designed to replace legacy military specification components in modern RF architectures.
