Abstract
RF circuitry, which includes a first hybrid RF coupler, a second hybrid RF coupler, a third hybrid RF coupler, and RF filter circuitry, is disclosed. The first hybrid RF coupler provides a first main port, a first pair of quadrature ports, and an isolation port. The second hybrid RF coupler provides a second main port and a second pair of quadrature ports. The third hybrid RF coupler provides a third main port and a third pair of quadrature ports. RF filter circuitry is coupled to the first pair of quadrature ports, the second pair of quadrature ports, and the third pair of quadrature ports. The first main port, the second main port, and the third main port provide main ports of the RF triplexer. The isolation port is a common port of the RF triplexer for coupling to an RF antenna.
