RF RECEIVE DIPLEXER

摘要

A first RF receive diplexer, which includes a first hybrid RF coupler, a second hybrid RF coupler, and RF filter circuitry, is disclosed. The first hybrid RF coupler has a first main port, a first pair of quadrature ports, and a first isolation port, which is coupled to an RF antenna. The second hybrid RF coupler has a second main port and a second pair of quadrature ports. The RF filter circuitry is coupled between the first pair of quadrature ports and the second pair of quadrature ports. The first RF receive diplexer receives a first adjunct RF antenna receive signal via the first isolation port to provide a first adjunct RF receive signal via the second main port. The first RF receive diplexer receives a first RF transmit signal via the first main port to provide a first RF antenna transmit signal via the first isolation port.
