4-Port Waveguide Crossguide Coupler

18 to 26.5 GHz, 40 dB Coupling, 20 dB Directivity, WR-42 Waveguide, K-Band
SKU:SWX-18327340-42-4B
SWX-18327340-42-4B is a four-port, split block cross guide coupler that is offered for power sampling where directivity is of concern. Compared to a traditional multi-hole directional coupler, cross guide couplers offer lower insertion loss and a smaller form factor package. This model operates between 18 to 26.5 GHz with 40 dB typical coupling, 0.4 dB nominal insertion loss, and 20 dB typical directivity. The input, output, and coupled ports are all WR-42 waveguides with UG-595/U compatible flanges.
