4-Port Waveguide Crossguide Coupler

SWX-40360320-19-4B 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 40 to 60 GHz with a 20 dB typical coupling level, 0.5 dB nominal insertion loss, and 20 dB typical directivity. The input, output, and coupled ports are all WR-19 waveguides with UG-383/U-M flanges.
