Circulators

Circulators are three or four-port waveguide components utilizing ferrite technology to selectively direct energy to a specific port based upon the direction of wave propagation. By placing a load on the port where reflected energy is directed, a three-port circulator can be made into an isolator. Richardson Electronics offers circulators, which can support power levels up to 100kW for L-band and 30kW for S-band.
