Crossguide Coupler (CGC)

The series CGC crossguide coupler covers 18 to 170 GHz in nine waveguide bands. The typical coupling value is 20 dB, with directivity of 17 dB up to 110 GHz and 12 dB above 110 GHz. For complete coverage of each waveguide band, two models are offered, each covering 70% of the waveguide band. Series CGC is offered with the fourth port (the isolated port) either internally terminated or left open.
