M3933/30-30S

Overview

The M3933/30-30S is a screened RF attenuator manufactured by Amphenol SV Microwave. It operates within the 2.92mm connector series, providing a fixed attenuation of 17 dB at a nominal impedance of 50 Ohms. The device supports a frequency range from 0 Hz to 32 GHz and handles a maximum power rating of 2 W. Designed for high-frequency applications, it features SMA single-row module packaging and functions as an in-line component.

Feature Summary

• Screened construction for enhanced environmental protection
• Fixed 17 dB attenuation value for signal reduction
• Compatible with 2.92mm connector interface standards

Applications

• High-frequency test and measurement setups
• Microwave communication systems requiring signal level control
• Defense and aerospace electronic subsystems

Procurement Notes

Verify the specific datasheet version and screening requirements before procurement. Confirm that the 2.92mm interface matches the system design. Ensure the 17 dB attenuation value aligns with circuit specifications. Check for RoHS compliance status if required by project regulations.

Selection Notes

Select this component when a precise 17 dB reduction is needed within the 32 GHz bandwidth. The 2.92mm interface ensures low VSWR performance compared to standard SMA connectors. Consider the 2 W power handling limit for thermal management in high-power environments.

Part Context

This part belongs to the M3933 series of screened RF attenuators. It utilizes the 2.92mm connector family, which offers superior performance up to 40 GHz. The 'S' suffix typically denotes a screened variant, distinguishing it from non-screened versions in the same product line.

Replacement Considerations

M3933/30-30N is a parameter-equivalent alternative offered by the same manufacturer.
