Dow-Key – Waveguide RF Switches
Waveguide RF switches are electromagnetic switches with hollow circular or rectangular cross-sections and are used for routing RF energy in microwave communications, broadcasting, and in radar applications. 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.
