W-Band Waveguide Bi-Directional Coupler (BDC-65110-10-10).pdf

    Model BDC-65110-10-10 is a W-band four port waveguide bi-directional coupler that provides a nominal coupling level of 10 dB and a minimum directionality of 30 dB in the full waveguide frequency band of 65 to 110 GHz. The four-port coupler uses traditional porous and block designs to achieve flat coupling levels, high directionality, and low insertion losses. The interface of the coupler is a WR-10 waveguide with UG-387/U M anti warping flange. Custom coupling levels can be provided under different models.
