M3933/30-19S

Overview

The M3933/30-19S is a fixed RF attenuator manufactured by Amphenol SV Microwave. It features SMA single-row connectors and operates within a frequency range of 0 Hz to 32 GHz. The component provides a nominal attenuation value of 9 dB with a 50 Ohm impedance. It is rated for a maximum power handling capacity of 2 Watts. Designed for high-reliability applications, this unit belongs to the 2.92mm series and is constructed to withstand rigorous environmental conditions.

Feature Summary

• Provides precise signal attenuation in high-frequency RF circuits
• Utilizes robust SMA connector interface for secure interconnects
• Engineered for operation across extreme temperature ranges

Applications

• Military radar systems requiring screened components
• Avionics communication equipment
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm connector gender orientation and screening requirements. Confirm RoHS3 compliance status prior to integration. Ensure compatibility with existing SMA mating interfaces. Validate that the 2W power rating meets system thermal constraints. Check for parameter-equivalent alternatives if supply chain constraints exist.

Selection Notes

Select this model when a 9 dB attenuation value is required within the 32 GHz bandwidth. Ensure the SMA connector type matches the circuit board or cable assembly. Verify that the 50 Ohm impedance aligns with the system design. Consider the screened construction requirement for sensitive military or aerospace environments where shielding is mandatory.

Part Context

This component is part of the M3933 series, which encompasses various fixed attenuators designed for microwave and radio frequency applications. The series includes multiple attenuation values and connector configurations. Amphenol SV Microwave produces these units to meet stringent MIL-Spec standards, ensuring reliability in demanding operational scenarios.
