M3933/30-12N

Overview

The M3933/30-12N is a 50 Ohm RF attenuator from the Amphenol SV Microwave 2.92mm series, designed for military specifications. It features a female-to-male connector configuration and provides attenuation at frequencies up to 32 GHz, with a maximum operational frequency of 40 GHz. The unit supports a power rating of 2 W and operates within a temperature range of -65 °C to +165 °C. This nonscreened variant is packaged in bulk.

Feature Summary

• Provides precise RF signal attenuation in high-frequency microwave circuits
• Supports operation in extreme thermal environments suitable for military applications
• Ensures stable impedance matching for signal integrity

Applications

• Satellite communication systems
• Military radar equipment
• Microwave test and measurement instrumentation

Procurement Notes

Verify the specific datasheet version (e.g., document 10887 or similar) to confirm exact attenuation values and physical dimensions. Ensure compatibility with 2.92mm mating connectors. Confirm RoHS3 compliance status if required by project specifications. Validate that the nonscreened construction meets the electromagnetic interference requirements of the intended installation environment.

Selection Notes

Select this component when a 2.92mm interface is required for frequencies extending to 40 GHz. Choose the nonscreened version if shielding is provided by the host assembly. Verify that the 2 W power handling capacity aligns with the system's peak power levels. Consider the operating temperature range to ensure reliability under environmental stress conditions.

Part Context
