M3933/30-11S

Overview

The M3933/30-11S is a connectorized RF attenuator manufactured by Amphenol SV Microwave. It features 2.92mm male to female connectors and operates within a frequency range of 0 Hz to 40 GHz. The component provides a maximum attenuation of 11 dB with a 50 Ohm impedance. It supports a power rating of 2 W and functions between -65°C and +165°C. Packaged in bulk, this screened unit meets military specifications for high-frequency signal management.

Feature Summary

• Provides fixed RF signal attenuation using precision 2.92mm interconnects
• Supports operation up to 40 GHz for high-frequency applications
• Constructed with screened housing for enhanced environmental protection

Applications

• Military radar systems requiring precise signal level control
• Test and measurement equipment operating at ultra-high frequencies
• Avionics communication subsystems needing stable attenuation

Procurement Notes

Verify the specific attenuation value against official datasheets, as suffix variations may indicate different dB ratings. Confirm that the screened version matches project requirements for environmental sealing. Ensure compatibility with existing 2.92mm infrastructure before procurement.

Selection Notes

Select this model when a fixed 11 dB attenuation is required up to 40 GHz. Consider the 2 W power handling capability for system integration. Verify temperature range suitability for extreme operational environments compared to commercial alternatives.

Part Context

This part belongs to the M3933 series of connectorized attenuators designed for rugged applications. It utilizes 2.92mm technology to maintain performance at higher frequencies than standard SMA components. The series is intended for defense and aerospace sectors requiring reliable signal conditioning.

Replacement Considerations

M3933/30-11N is a parameter-equivalent alternative from the same manufacturer. Cross-check connector gender and attenuation tolerance with Radiall equivalents if sourcing from other vendors.
