TECHNICAL DATA SHEET

The PEWCP1059 is a WR-90 crossguide waveguide coupler that operates in the frequency range of 8.2 to 12.4 GHz. This

Waveguide component has a typical VSWR of 1.05:1. These designs are made of painted copper alloy and incorporate a

cross wall configuration that result in a mid-band nominal coupling value of 20, 30, 40 or 50 dB. Common applications for this

component would be where power measurements are required within a system for measuring/sampling power or frequency

monitoring with minimal signal loss to the main transmission line. This WR-90 waveguide coupler uses grooved CPR-90

flanges. Pasternack offers a complete family of waveguide Crossguide and Top wall couplers that are in-stock and ship same

day.
