Welcome
Welcome to the RF Switch Design Project web
site.....
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.
