This is a WR340 Waveguide Switch that is used to switch an input waveguide to either the A or B output port, these waveguide switches are typically used in satellite and microwave communications to switch high power RF equipment safely. The WR340 Waveguide Switch can be supplied in a range of configurations allowing it to be integrated with any existing waveguide redundancy or switching system. These waveguide switches can be controlled in a manual physical manner or electrically in an automatic system with control logic.
Waveguide RF switches are electromagnetic switches with hollow rectangular cross-sections and are used for routing RF energy. Waveguide switches can be used to transfer both power and communication signals, and the bandwidth of a waveguide is in relation to its size, and thus always referred to by its size (e.g. WR112, WR90, WR75 etc.). Compared to coaxial RF switches, waveguides can route extremely high power signals over a narrow bandwidth at low to high frequencies, and now Lightweight Waveguide series is available.
