4-Port Waveguide Crossguide Coupler

SWX-71386320-12-4B is a four-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 71 to 86 GHz with a 20 dB typical coupling level, 0.7 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.
