Publikováno v: 2017 47th European Microwave Conference (EuMC).

A silicon micromachined waveguide hybrid coupler for J-band (220-325 GHz) applications is presented. The coupling and phase shifting functions are realised using a 90° ridged waveguide phase shifter, a joint waveguide section and a port extension. T
