PE-W42AT001-30

Overview

The PE-W42AT001-30 is a WR-42 waveguide continuously variable attenuator manufactured by Pasternack. It operates within the frequency range of 18 GHz to 26.5 GHz and provides an attenuation adjustment from 0 dB to 30 dB. The component features a UG-595/U square cover flange interface and includes a dial for design adjustments. It is rated for a power handling capacity of 300 mW.

Feature Summary

• Continuously variable attenuation control via mechanical dial
• WR-42 waveguide band compatibility with UG-595/U flanges
• Designed for precise signal level adjustment in high-frequency applications

Applications

• Waveguide test and measurement systems
• Microwave communication equipment signal conditioning
• Radar system calibration and testing

Procurement Notes

Verify the specific model designation against official Pasternack documentation to ensure correct WR-42 waveguide specifications and UG-595/U flange compatibility. Confirm that the required attenuation range and power rating align with system requirements before procurement. Check for any updated datasheets or compliance certifications relevant to the intended application environment.

Selection Notes

Select this component when continuous, adjustable attenuation is required within the 18 to 26.5 GHz frequency spectrum. Ensure the system utilizes WR-42 waveguide interfaces compatible with UG-595/U flanges. Consider the 300 mW power limit and the need for manual dial adjustment when integrating into the signal chain.

Part Context

This part belongs to Pasternack's RF Variable Attenuators series, specifically designed for waveguide applications. It complements other WR-42 components such as phase shifters and bends, providing essential signal control capabilities for instrumentation-grade microwave systems operating in the K-band frequency range.

Replacement Considerations

Direct substitutes may include other Pasternack WR-42 continuously variable attenuators with similar flange types and frequency ranges. Verify interface compatibility and performance specifications before substitution.
