The loss from port-1 to port-3 is known as Isolation which is quite high (about 20 to 25 dB). This is due to the fact that insertion loss of circulator is loss from 1 to 2 which is very less (few tenths of a dB). This means signal input at port-1 will give out signal from port-2 and there should not be The figure-1 depicts anti-clockwise circulator.Īs shown here signal flows from port 1 to 2, from port-2 to 3 and from port-3 to 1. clockwise circulator and anti-clockwise circulator.
The RF circulators are available in waveguide or stripline forms.īased on direction of signal travel in the circulator there are two major types The 3 port circulator is known as Y-Junction Circulator. The circulator device which operates on radio or microwave frequency is known as Input from port-N will lead to output at N+1 port is known as circulator. It mentions how RF Circulator works along with its terminal diagram.ĭefinition: The non-reciprocal ferrite device which consists of 3 or more ports in which
