Short Tutorial: Understanding RF Isolator and RF .

A circulator is a passive, non-reciprocal device, usually with three or four ports. Once a signal enters one port it is transmitted to the next port following a prescribed circulation path. Based on how signals "circulate" once inside the circulator, there are two types: clockwise (CW) and counterclockwise (CCW).
