M3933/30-19N

Overview

The M3933/30-19N is a 2.92mm female-to-male RF attenuator manufactured by Amphenol SV Microwave. It provides a fixed attenuation of 9 dB with a 50 Ohm impedance. The component operates within a frequency range of 0 Hz to 32 GHz and supports a maximum power rating of 2 W. It is designed for military specifications, functioning between -65°C and +165°C.

Feature Summary

• Military-grade construction ensuring reliability in harsh environments
• Fixed 9 dB attenuation for precise signal control
• High-frequency operation up to 32 GHz
• Robust thermal performance across extreme temperature ranges

Applications

• Military radar systems
• Avionics signal processing
• Test and measurement equipment
• Defense communication networks

Procurement Notes

Verify the suffix 'N' indicates nickel plating on the connector interface. Confirm the specific attenuation tolerance and VSWR values against the official datasheet before integration. Ensure environmental sealing requirements match the application's exposure conditions.

Selection Notes

Select this model when a 9 dB fixed loss is required in a 2.92mm form factor. Compare against screened variants if shielding is necessary. Verify that the 2W power handling meets system peak power demands without derating issues at elevated temperatures.

Part Context

This part belongs to the M3933 series of RF attenuators from Amphenol SV Microwave. These components are engineered for high-reliability applications requiring stable performance at microwave frequencies. The series offers various attenuation values within the same mechanical footprint.

Replacement Considerations

M3933/30-19S is a parameter-equivalent alternative with different plating.
