M3933/25-09S

Overview

The M3933/25-09S is a fixed RF attenuator manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It provides a nominal attenuation of 9 dB with a maximum power rating of 2 W. The component operates within a frequency range of 0 Hz to 2 GHz and features SMA connectors in an in-line module configuration. Designed for military applications, it complies with MIL-DTL-M3933 standards.

Feature Summary

• Complies with MIL-DTL-M3933 qualification requirements for defense electronics
• Utilizes SMA connector interface for reliable signal transmission
• Engineered for high-power handling up to 2 W dissipation

Applications

• Military communication systems requiring precise signal reduction
• Aerospace test and measurement instrumentation
• Defense electronic equipment signal conditioning

Procurement Notes

Verify that the specific part number matches the required 9 dB attenuation and 2 GHz frequency limit. Confirm compliance with MIL-DTL-M3933 specifications for intended military or aerospace deployment. Ensure SMA connector gender and mating compatibility are validated against system requirements before procurement.

Selection Notes

Select this model when a 9 dB fixed attenuation value is required within the 0 Hz to 2 GHz bandwidth. Consider the 2 W power rating for high-power signal paths. Verify that the SMA in-line module form factor fits the physical constraints of the assembly compared to higher-frequency variants like the 12.4 GHz or 18 GHz series.

Part Context

This component belongs to the M3933/25 series of connectorized attenuators from Cinch Connectivity Solutions. The series offers various attenuation values across different frequency ranges, including 12.4 GHz and 18 GHz options. The M3933/25-09S specifically targets lower frequency applications within this standardized military-grade product line.

Replacement Considerations

M3933/25-09N serves as a direct substitute variant within the same series.
