4-Port Waveguide Crossguide Coupler

SWX-17426420-04-4B is a four-port, split block crossguide coupler that is offered for power sampling where directivity is of no 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 170 to 260 GHz with a 20 dB typical coupling level and 2.5 dB nominal insertion. The input, output, and coupled ports are all WR-04 waveguides with UG-387/U-M anti-cocking flanges.
