M3933/25-84N

Overview

The M3933/25-84N is a radio frequency military specification connector manufactured by Amphenol SV Microwave. It functions as an SMA male to female attenuator with a nominal attenuation of 16 dB and a characteristic impedance of 50 Ohms. The component supports a maximum frequency of 18 GHz and operates within a temperature range of -65 °C to +165 °C. It is supplied in bulk packaging.

Feature Summary

• Provides fixed signal attenuation for RF applications
• Compatible with SMA interface standards
• Designed for high-temperature military environments

Applications

• RF test and measurement systems
• Military communication equipment
• Signal conditioning circuits

Procurement Notes

Verify the specific suffix 'N' against official manufacturer documentation to confirm non-screened status, as screened variants exist within this series. Ensure compatibility with MIL-DTL-39012 requirements if mandated by system specifications. Confirm that the 16 dB attenuation value aligns precisely with circuit design needs before procurement.

Selection Notes

Select this model when a fixed 16 dB loss is required at frequencies up to 18 GHz. Consider the operating temperature range of -65 °C to +165 °C for harsh environment deployment. Compare against screened versions if environmental sealing is necessary, noting that the 'N' suffix typically denotes non-screened construction.

Part Context

This component belongs to the M3933 series of connectorized attenuators from Amphenol SV Microwave. These parts are designed to meet rigorous military standards for reliability and performance in demanding RF applications. The series offers various attenuation values while maintaining consistent SMA interface characteristics.

Replacement Considerations

M3933/25-84S is a screened variant with identical electrical parameters.
