US10686485B1 - High isolation duplexer/quasi circulator .

A high isolation duplexer/quasi circulator with two quadrature couplers is disclosed. Isolation between a transmit (TX) port and receive (RX) port of the quasi circulator is improved through use of two quadrature couplers. The quadrature couplers are coupled such that a first TX-RX signal path (from the TX port to the RX port) is shifted at or near 180 degrees from a second TX-RX signal path.

CIRCULATOR - Valvo

A measure of the separation of signal levels on adjacent ports of a Circulator is called as Isolation. It is measured in dB.The greater the isolation value, the lesser will be the interference from a signal on one port relative to an adjacent port. This isolation is due to a matched termination attached to one of the three ports of the Circulator.
