The FMWCP1069 is a WR-112 crossguide waveguide coupler that operates in the

frequency range of 7.05 to 10 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 maintransmission line. This

WR-112 waveguide coupler uses grooved CPR-112 flanges. Fairview offers a

complete family of waveguide Crossguide and Top wall couplers that are in-stock

and ship same day.
