M3933/25-70S

Overview

The M3933/25-70S is a fixed RF attenuator module manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a nominal attenuation of 6 dB with a power rating of 2 W. The device operates within a frequency range of 0 Hz to 18 GHz and maintains a characteristic impedance of 50 Ohms. It utilizes SMA connectors in an inline configuration, designed for high-reliability applications requiring precise signal reduction.

Feature Summary

• Provides fixed 6 dB attenuation for signal level control
• Operates up to 18 GHz for wideband RF applications
• Supports 2 W power handling capacity
• Features SMA connector interface for direct integration

Applications

• Military communication systems
• Aerospace test and measurement equipment
• Defense electronic signal conditioning
• Harsh environment RF circuitry

Procurement Notes

Verify the specific suffix 'S' against official manufacturer documentation to confirm connector gender and screening requirements. Ensure compatibility with MIL-DTL-M3933 standards if military qualification is required. Confirm that the 18 GHz frequency range meets system specifications before procurement.

Selection Notes

Select this component when a fixed 6 dB reduction is needed at frequencies up to 18 GHz. Consider the 2 W power rating for appropriate thermal management. Verify SMA interface compatibility with existing PCB or cable assemblies. Ensure the inline module form factor fits the mechanical constraints of the design.

Part Context

This part belongs to the M3933/25 series of connectorized attenuators from Midwest Microwave. These components are typically used in demanding environments where reliability and consistent performance across wide bandwidths are critical. The series supports various attenuation values and connector types.

Replacement Considerations

Check for exact cross-reference part numbers such as M3933/25-70N or other suffix variants from the same manufacturer family. Verify that any substitute matches the 6 dB attenuation, 18 GHz limit, and 2 W power rating exactly.
