Abstract	The two-port reflection gyromagnetic waveguide switch described in this paper consists of a 90° Faraday rotator in a re-entrant or an inverted re-entrant turnstile geometry in the E-plane at the junction of two H-plane rectangular waveguides. It adjustment is a two-step eigenvalue problem. One adjustment fixes the electrical length of the circular Faraday rotator waveguide and produces a passband in its frequency response and the other fixes its gyrotropy and produces a stopband there. This paper also includes the separate synthesis of the passband condition in a WR75 waveguide at a frequency of 13.25 GHz using two different processes. The switch has two passband conditions at the design frequency, each of which is verified experimentally The stopband is separately established experimentally by magnetizing the gyromagnetic resonator.
