M3933/25-46N

Overview

The M3933/25-46N is a fixed RF attenuator manufactured by Amphenol SV Microwave, designed for military specifications. It features SMA male to female connectors with a 50-ohm impedance and operates up to 18 GHz. The unit provides an attenuation value of 46 dB and utilizes a non-screened bulk package configuration. It supports a maximum operating temperature of +165°C and a minimum of -65°C.

Feature Summary

• Military-grade construction compliant with MIL-Spec standards
• SMA connector interface for secure RF signal transmission
• High-temperature stability suitable for extreme environments

Applications

• Satellite communication systems
• Microwave circuit power level adjustment
• RF test and measurement equipment

Procurement Notes

Verify the specific datasheet version for the M3933/25-46N to confirm exact electrical tolerances and mechanical dimensions prior to integration. Ensure that the non-screened packaging meets the electromagnetic interference requirements of the target application environment. Cross-reference the manufacturer's latest documentation to validate compliance with current military specification updates.

Selection Notes

Select this component when a high attenuation value is required within the SMA frequency range. The 46 dB rating distinguishes it from lower attenuation variants in the same series. Consider the non-screened design if shielding is provided by the host enclosure. Verify thermal management capabilities given the high-temperature operational limits.
