PE-W12AT002-30

Overview

The Pasternack PE-W12AT002-30 is a WR-12 waveguide continuously variable attenuator designed for the 60 GHz to 90 GHz frequency range. It provides an attenuation adjustment from 0 dB to 30 dB with a dial control mechanism. The component features UG-387/U round cover flanges for secure waveguide interface connections. It operates at a maximum power level of 100 mW and maintains a characteristic impedance of 50 Ohms. This unit is part of the RF variable attenuators series and is packaged in bulk.

Feature Summary

• Continuously variable attenuation control via integrated dial mechanism
• WR-12 waveguide interface with UG-387/U round cover flanges
• Designed for high-frequency operation between 60 GHz and 90 GHz

Applications

• Millimeter-wave test and measurement systems
• Radio frequency signal path power management
• Waveguide circuit calibration and characterization

Procurement Notes

Verify the specific datasheet version for the PE-W12AT002-30 to confirm current mechanical dimensions and electrical tolerances. Ensure that the UG-387/U flange mating surfaces are compatible with existing waveguide infrastructure. Confirm that the 100 mW power rating aligns with the system's maximum signal levels to prevent component damage during operation.

Selection Notes

Select this model when continuous, precise attenuation adjustment is required within the WR-12 band. The dial-operated design facilitates manual tuning in laboratory environments. Consider the 50 Ohm impedance match for integration into standard RF systems. Evaluate the bulk packaging format against handling requirements for sensitive waveguide components.

Part Context

This component belongs to Pasternack’s line of connectorized attenuators, specifically targeting millimeter-wave applications. It utilizes standard WR-12 waveguide dimensions to ensure interoperability with common test equipment. The product falls under the sub-category of attenuators within the broader RF interconnects classification, serving as a critical passive element for signal level control.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users requiring alternative attenuation ranges or different waveguide sizes must consult the manufacturer's full catalog for compatible WR-12 models.
