M3933/25-47S

Overview

The M3933/25-47S is a fixed RF attenuator manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It provides a nominal attenuation of 21 dB with a maximum frequency range of 0 Hz to 12.4 GHz. The device features SMA connectors and operates at a power rating of 2 W. It has a characteristic impedance of 50 Ohms and functions within a temperature range of -55 °C to +125 °C.

Feature Summary

• Provides precise 21 dB signal attenuation for RF applications
• Operates up to 12.4 GHz frequency range
• Features SMA male/female connector interface
• Rated for 2 W power handling capacity

Applications

• Military aerospace RF systems
• Test and measurement instrumentation
• Communication equipment signal conditioning

Procurement Notes

Verify the specific suffix 'S' indicates screened configuration against official datasheets. Confirm RoHS compliance status as military variants often differ from commercial standards. Ensure SMA gender compatibility matches system requirements before ordering.

Selection Notes

Select this model when 21 dB attenuation is required within the 12.4 GHz bandwidth. Verify that the 2 W power rating meets system peak power levels. Check if the screened variant is necessary for environmental protection in harsh conditions.

Part Context

This component belongs to the M3933/25 series of connectorized attenuators. It is designed for high-reliability applications requiring stable attenuation values across wide frequency bands. The series supports various attenuation values and connector types.

Replacement Considerations

M3933/25-47N serves as a non-screened alternative with identical electrical specifications. Verify mechanical dimensions and connector gender compatibility when substituting.
