PE-W12AT002A-30

Overview

The Pasternack PE-W12AT002A-30 is a WR-12 waveguide continuously variable attenuator designed for high-frequency applications. It operates within a frequency range of 60 GHz to 90 GHz and provides an attenuation adjustment from 0 dB to 30 dB. The device features a UG-387/U round cover flange interface and includes a dial mechanism for precise control. It supports a power rating of 2W and maintains a VSWR of up to 1.75:1, ensuring signal integrity in demanding RF environments.

Feature Summary

• Continuously variable attenuation capability allowing precise signal level control
• WR-12 waveguide design optimized for millimeter-wave frequencies
• Integrated dial mechanism for manual adjustment of attenuation levels

Applications

• Millimeter-wave test and measurement systems
• Satellite communication link testing

Procurement Notes

Verify the specific model suffix and flange type against your system requirements before ordering. Confirm that the operating frequency range aligns with your application needs. Check for any required accessories or mounting hardware not included in the standard package. Ensure compatibility with existing waveguide components and connectors.

Selection Notes

Select this component when continuous attenuation adjustment is required in the 60-90 GHz band. Consider the 2W power handling limit for your specific signal levels. Evaluate the need for a dial-operated mechanism versus remote-controlled alternatives. Ensure the WR-12 waveguide size matches your infrastructure constraints.
