M3933/25-07N

Overview

The M3933/25-07N is a fixed RF attenuator manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It provides a nominal attenuation of 7 dB with a maximum power rating of 2 W. The component operates within a frequency range of 0 Hz to 2 GHz and utilizes SMA connectors in an inline module configuration. Designed for military applications, it complies with MIL-DTL-M3933 standards.

Feature Summary

• Complies with MIL-DTL-M3933 specifications for qualified parts list (QPL) reliability
• Features SMA connector interface for secure signal transmission
• Constructed as a coaxial inline module for direct circuit integration

Applications

• Military electronic systems requiring standardized attenuation
• Aerospace communication equipment testing
• Defense radar signal processing chains

Procurement Notes

Verify the specific suffix 'N' against official manufacturer documentation to confirm compliance with MIL-DTL-M3933 requirements. Ensure that the SMA connector gender and mating compatibility match the system design. Confirm RoHS status and environmental ratings prior to procurement to align with project specifications.

Selection Notes

Select this component when a precise 7 dB attenuation is required within the 0 Hz to 2 GHz bandwidth. The 2 W power handling capacity suits moderate signal levels. Verify that the SMA inline form factor fits the physical constraints of the assembly. Consider temperature stability if operating near the specified limits.

Part Context

This part belongs to the M3933/25 series of connectorized attenuators from Cinch Connectivity Solutions. The series offers various attenuation values while maintaining consistent SMA interfaces and military-grade construction. These components are designed for high-reliability environments where signal integrity and standard compliance are critical.

Replacement Considerations

Direct substitutes include other M3933/25 series variants with identical 7 dB attenuation and SMA interfaces. Cross-reference with MIL-DTL-M3933 compliant equivalents from authorized manufacturers to ensure mechanical and electrical equivalence.
