A circulator is a passive, non-reciprocal device with three or more ports used to transmit microwave energy in a specific direction.

Price Guide: POA

Additionally, circulators are used to prevent reflected microwave energy from the magnetron preventing excessive magnetron heating or moding.

An isolator is a circulator with an absorbing load attached to the port used to transmit the reflected energy.

In a typical microwave circuit, microwave energy is generated from the magnetron and is transmitted to the load where any reflected energy directed to the load port and absorbed.
