CSS short slot hybrid coupler

The series CSS short slot hybrid coupler covers 26.5 to 170 GHz in nine waveguide bands. The two output ports are in-line to the input port, and have 90° phase difference with nearly equal power levels over 5% of the center frequency. Isolation between output ports is 20 dB (typical).
