M3933/30-16N

Overview

The M3933/30-16N is a non-screened RF attenuator manufactured by Amphenol SV Microwave. It utilizes 2.92mm connectors with a male-to-female configuration and maintains a 50 Ohm impedance. The device operates within a frequency range of 0 Hz to 40 GHz, featuring a maximum attenuation of 7.5 dB. It supports a power rating of 2 W and functions reliably between -65°C and +165°C.

Feature Summary

• Incorporates 2.92mm connector interface for high-frequency signal integrity
• Provides fixed attenuation value for precise signal level control
• Designed for operation in extreme temperature environments

Applications

• Military radio systems requiring screened or non-screened attenuation
• Test and measurement instrumentation up to 40 GHz
• Aerospace communication equipment

Procurement Notes

Verify the specific suffix 'N' indicates non-screened construction versus 'S' for screened variants. Confirm that the 2.92mm interface matches system requirements. Ensure environmental ratings meet operational extremes. Check datasheet for exact attenuation tolerance specifications.

Selection Notes

Select this component when a 7.5 dB fixed attenuation is required at frequencies up to 40 GHz. The 2.92mm interface offers superior performance compared to SMA types. Consider the non-screened variant if shielding is provided externally. Verify power handling capabilities against peak signal levels.

Part Context

This part belongs to the M3933 series of connectorized attenuators from Amphenol SV Microwave. These components are designed for military and aerospace applications. The series includes various attenuation values and connector types. The 2.92mm variant extends the usable frequency range beyond standard SMA limits.

Replacement Considerations

M3933/30-16S is the screened equivalent. M3933/30-25N offers 12 dB attenuation. M3933/30-21S provides 10 dB attenuation in a screened package. Verify interface compatibility before substitution.
