Radio frequency front end circuitry comprises a first antenna port, a second antenna port, antenna switching circuitry, a first diplexer, and a second diplexer. The antenna switching circuitry is coupled to each of the first antenna port and the second antenna port through the first diplexer and the second diplexer, respectively. The antenna switching circuitry is adapted to selectively couple one or more of a plurality of transmit and receive ports to the first antenna port and the second antenna port. |
