1. Radio frequency (RF) front end circuitry comprising:
- a plurality of RF front end ports;
a first antenna port configured to be coupled to a first antenna and a second antenna port configured to be coupled to a second antenna;
front end switching circuitry configured to selectively couple one or more of the plurality of RF front end ports to one or more of the first antenna port and the second antenna port;
a first diplexer coupled between the front end switching circuitry and the first antenna port and a second diplexer coupled between the front end switching circuitry and the second antenna port; and
control circuitry configured to, in a carrier aggregation mode of operation of the RF front end circuitry, operate the front end switching circuitry to selectively couple at least four of the plurality of RF front end ports to one of the first antenna port and the second antenna port.

Abstract
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.
