Appliction of Circulator Normally, three prot circulators are used as duplexers. Connection a transmitter to port 1, antenna to port 2, and receiver to port 3 permits simultaneous transmission and reception of signals while protecting the transmitter from reflections due to antenna mismatch. In high power systems, a limiter is commonly used between port 3 and the receiver to prevent receive burnout. Another common use of circulators is as coupling elements is reflection
