Model SWX-31339330-28-4B is a Ka-band split-block crossguide coupler. Crossguide couplers are 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 30 dB typical coupling level, 0.3 dB typical insertion loss, and 15 dB typical directivity. The input, output, and coupled ports are all WR-28 waveguides with UG-599/U flanges.
