Background

This project aims to develop a 94 GHz 3-port switching circulator for Millitech Corporation of Northampton, Massachusetts. A circulator is a microwave component which directs microwave energy from input ports to output ports in a circular fashion, with the ports being highly isolated in the reverse direction. This is accomplished with a specialized type of ferrite magnet. Switching circulators allow the direction of circulation to be reversed.

Circulators can be used to isolate RF components from each other in one direction so that a high power component does not damage other components if a mistake is made. Circulating devices are ideal for antenna interfaces because they can be used in transceivers to join a receiver and transmitter to a single antenna. They can be very advantageous in microwave design because of their low loss characteristics and high power handling capability. Switching circulators act as switches directing input energy on one port to either of the two others depending on the switching state.
