Circulator & Isolator
Circulator
It is a multiport junction in which a wave can flow only from nth port to (n+1)th port in one direction. Although there is no restriction on the number of ports, the three port microwave circulator generally used.

Isolator
An Isolator is a non reciprocal transmission device that is used to isolate one component from reflections of other components in the transmission lines. An ideal isolator completely absorbs the power for propagation in one direction and provides lossless transmission in the opposite direction.
