Abstract
Radio frequency (RF) front-end circuitry and methods of operating the same are described. One apparatus includes multiple antennas and a RF front-end circuitry. The RF front-end circuitry includes a first diplexer, a second diplexer, a third diplexer, a fourth diplexer, and a switch. A first transceiver is coupled to a first antenna via the first diplexer and the second diplexer. The third receiver is coupled to the first antenna via the first diplexer. The second transceiver is selectively coupled to a second antenna via the third diplexer, the switch, and the fourth diplexer when the switch is set to the first mode in response to the control signal from a processing component. The first transceiver is selectively coupled to the second antenna via the switch and the third diplexer when the switch is set to the first mode in response to the control signal from the processing component.
