Circulator is a passive electronic component with three or more ports in which the ports can be accessed in such an order that when a signal is fed into any port it is transferred to the next port, the first port being counted as following the last in numeric order. When one port of a three port circulator is terminated in a load, it can be referred to as an isolator.
There are circulators for VHF, UHF, microwave frequencies and for light, the latter being used in optical fiber networks. Circulators fall into two main classes: 4-port waveguide circulators based on Faraday rotation of propagating waves in a magnetized material, and 3-port "turnstile" or "Y-junction" circulators based on cancellation of waves propagating over two different paths near a magnetized material. Waveguide circulators may be of either type, while more compact devices based on stripline cables are of the 3-port type. Sometimes two or more Y-junctions are combined in a single component to give four or more ports, but these differ in behavior of a true 4-port circulator.
