M3933/25-75N

Overview

The M3933/25-75N is a military-grade RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a fixed attenuation value of 8.5 dB with a nominal impedance of 50 Ohms. The device operates within a frequency range of 0 Hz to 18 GHz and supports a power rating of 2 Watts. It utilizes SMA in-line module connectors for signal transmission.

Feature Summary

• Complies with MIL-DTL-M3933 specifications for military qualification
• Features SMA in-line module connector interface
• Designed for high-frequency RF signal attenuation applications

Applications

• Military communication systems
• Aerospace electronic testing equipment
• Harsh environment RF signal conditioning

Procurement Notes

Verify the specific suffix 'N' against the official manufacturer datasheet to confirm compliance with current MIL-DTL-M3933 standards. Ensure the required attenuation value of 8.5 dB matches system design requirements before procurement, as this component is not RoHS compliant.

Selection Notes

Select this model when an 8.5 dB fixed attenuation is required at frequencies up to 18 GHz. The SMA in-line configuration suits board-level or chassis-mount integration. Verify that the 2W power handling capacity aligns with the maximum input signal levels expected in the target application circuit.

Part Context

This component belongs to the M3933/25 series of connectorized attenuators from Midwest Microwave. The series offers various fixed attenuation values while maintaining consistent electrical performance and mechanical form factors suitable for defense and aerospace sectors requiring reliable RF components.

Replacement Considerations

Compatible substitutes include other M3933/25 series variants with different attenuation values, such as M3933/25-62N (2dB) or M3933/25-30S (4dB), provided the specific attenuation requirement differs. Ensure any replacement maintains the same SMA interface and 50 Ohm impedance.
