SWJ-08-M1 is a F-band manual waveguide switch that covers the frequency range of 90 to 140 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 1.6 dB and 50 dB, respectively. The RF ports are WR-08 waveguides with UG-387/U-M anti-cocking flanges.
