A Waveguide Switch is an electromechanical or manual relay for RF signals. The most common type of RF switches consists of DPDT (Double Pole Double Throw) both failsafe and latching, with or without position indicators.
Waveguide Switches have a square stator with four waveguide ports. The rotor, which is fitted in the stator, has two or three channels. Electrical continuity between rotor and stator is achieved by means of quarter wave chokes. These chokes provide extremely high isolation between the channels while ensuring unchanged high electrical performance throughout the lifetime of the switch.
EVERAXIS Mechanical Waveguide Switches provide high isolation, low insertion loss, high power capability and a long life. For all latching models, the current is automatically switched off when the rotor is in position. One or several sets of position indicators are available with all models of actuators. Some models can be supplied with a manual override knob for manual position setting.
