M3933/30-03N

Overview

The M3933/30-03N is a fixed RF attenuator manufactured by Amphenol SV Microwave, designed for high-frequency applications. It features SMA male-to-female connectors and operates within a frequency range of DC to 32 GHz. The component provides an attenuation value of 1 dB with a 50 Ohm impedance. It supports a power rating of 2 W and functions reliably across a temperature range of -65°C to +165°C. Packaged in bulk, this non-screened unit is part of the military-grade M3933 series.

Feature Summary

• Military-grade construction suitable for harsh environments
• Wide operational frequency range up to 32 GHz
• High thermal stability with extended temperature ratings
• Fixed 1 dB attenuation for precise signal control

Applications

• Satellite communication systems
• Microwave circuit testing and measurement
• Defense and aerospace radar subsystems
• High-frequency signal generation equipment

Procurement Notes

Verify the specific connector gender configuration (Male/Female) against schematic requirements before ordering. Confirm that the non-screened housing meets the electromagnetic interference shielding needs of the target assembly. Ensure the operating environment stays within the specified -65°C to +165°C range to maintain performance integrity and prevent thermal degradation of the internal resistive elements.

Selection Notes

Select this model when a low attenuation value of 1 dB is required for impedance matching or signal conditioning in high-frequency circuits. Consider the SMA interface compatibility with existing board layouts. Evaluate the need for screened versus non-screened variants based on the system's EMI sensitivity. Verify that the 2W power handling capacity aligns with the maximum expected signal levels in the application path.
