Abstract:
Radio frequency (RF) front end circuitry includes one or more antenna ports, one or more RF switching ports, and an RF switch matrix coupled between the antenna ports and the RF front end ports. The RF switch matrix comprises a dual 4×4 multiplexer, and is adapted to selectively couple any one of the antennas to any one of the plurality of RF switching ports.
