4-Port Waveguide Crossguide Coupler

SWX-31339320-28-4B 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 smaller form factor and insertion length. This model operates between 31 to 39 GHz with a 20 dB typical coupling level, 0.4 dB nominal insertion loss, and 15 dB typical directivity. The input, output, and coupled ports are all WR-28 waveguides with UG-599/U compatible flanges.
