M3933/30-28S

Overview

The M3933/30-28S is a screened RF attenuator manufactured by Amphenol SV Microwave, designed for high-frequency applications. It features a 2.92mm female-to-male connector configuration and operates within a frequency range of DC to 32 GHz, with a maximum rated frequency of 40 GHz. The component provides a fixed attenuation value of 16 dB at a characteristic impedance of 50 Ohms. It supports a power rating of 2 Watts and functions reliably across an operating temperature range of -65°C to +165°C.

Feature Summary

• Screened construction for enhanced signal integrity in military-grade environments
• Compatible with 2.92mm interface standards for high-frequency performance
• Fixed attenuation design ensuring stable signal reduction

Applications

• Military radar systems requiring precise signal attenuation
• Test and measurement equipment operating up to 40 GHz
• Avionics communication subsystems

Procurement Notes

Verify the specific suffix 'S' indicates the screened variant when sourcing replacements. Confirm that the 2.92mm gender configuration matches the system requirements. Ensure the 16 dB attenuation value aligns with the circuit design specifications. Check for RoHS compliance status if environmental regulations apply to the project.

Selection Notes

Select this component when a fixed 16 dB attenuation is required for 2.92mm interfaces. Consider the 40 GHz maximum frequency capability for wideband applications. Evaluate the 2W power handling against the expected signal levels. Verify the screened requirement is necessary for the specific electromagnetic interference environment.

Part Context

This part belongs to the M3933 series of RF attenuators from Amphenol SV Microwave. The series includes various attenuation values and connector types, such as SMA and 2.92mm. The M3933/30-28S specifically utilizes the 2.92mm interface, distinguishing it from SMA-based variants like the M3933/25 series.
