Abstract
An isolation circulator network includes three circulators and a 180 degree ybrid coupler for isolating an RF transmitter from a nearby RF receiver. The isolation circulator network comprises: a first circulator for transforming a first RF signal, RF.sub.1, into a second RF signal, RF.sub.2 and a third RF signal, RF.sub.3 ; a second circulator for throughputting the third RF signal; a third circulator for transforming the second RF signal into a fourth RF signal, RF.sub.4, and a fifth RF signal, RF.sub.5, and for throughputting a sixth RF signal, RF.sub.6 ; and a 180-degree hybrid coupler which provides a seventh RF signal, RF.sub.7 in response to receiving the third, fifth, and sixth RF signals, where RF.sub.7 =(RF.sub.5 -RF.sub.3 +RF.sub.6).
