3-Port Waveguide Crossguide Coupler

SWX-60390315-12-3B is a three-port, split block crossguide coupler that is offered for power sampling where directivity is of concern. Compared to a multi-hole directional coupler, crossguide couplers offer lower insertion loss and a shorter insertion length. This model operates between 60 to 90 GHz with a 15 dB typical coupling level, 0.6 dB nominal insertion loss, and 15 dB typical directivity. The input, output, and coupled ports are all WR-12 waveguides with UG-387/U anti-cocking flanges.
