M3933/30-04S

Overview

The M3933/30-04S is a fixed RF attenuator manufactured by Amphenol SV Microwave, belonging to the 2.92mm series. It features a female-to-male connector configuration with a nominal attenuation of 1.5 dB. The component operates within a frequency range of DC to 32 GHz and maintains a 50 Ohm impedance. It supports a maximum power rating of 2 W and functions reliably across an operating temperature range of -65°C to +165°C.

Feature Summary

• Provides precise signal attenuation in high-frequency RF circuits
• Ensures stable performance across extreme temperature environments
• Features robust construction suitable for screened applications

Applications

• High-frequency test and measurement instrumentation
• Wireless communication systems requiring signal level adjustment
• Military and aerospace electronic subsystems

Procurement Notes

Verify that the specific suffix 'S' denotes the screened variant required for your application environment. Confirm that the 1.5 dB attenuation value aligns with circuit design specifications. Ensure compatibility with 2.92mm mating connectors and validate thermal management capabilities for the intended operating temperature range.

Selection Notes

Select this model when a 1.5 dB fixed attenuation is required at frequencies up to 32 GHz. Consider the 2 W power handling capability and the wide temperature range for harsh environment deployments. Compare against other values in the M3933/30 series if different attenuation levels are needed.

Part Context

This component is part of the M3933 family of connectorized attenuators from Amphenol SV Microwave. These devices are designed for high-reliability applications, offering consistent electrical performance and mechanical durability.
