SWJ-05-M1 is a G-band manual waveguide switch that covers the frequency range of 140 to 220 GHz. The switch is a E-plane type, bi-directional, multi-path device with a 3-channel rotor which allows for switching between four distinct positions. The typical insertion loss and isolation are 3 dB and 40 dB, respectively. The RF ports are WR-05 waveguides with UG-387/U-M anti-cocking flanges.
