CPC H01Q 3/267 (2013.01) [H01Q 3/42 (2013.01); H04B 1/04 (2013.01); H04B 2001/0425 (2013.01)] | 24 Claims |
1. A transceiver circuit comprising:
a) switchable transmit and receive RF processing paths, each selectively configured to operate according to one of:
a1) a transmit path for transmission of an RF signal through a respective element of a plurality of elements of an antenna array, or
a2) a receive path for reception of an RF signal through the respective element of the antenna array;
b) switchable feedback paths selectively coupled to the switchable transmit and receive RF processing paths via switchable elements of said feedback paths; and
c) one or more RF combiners coupled to the switchable feedback paths,
wherein said switchable feedback paths are selectively configured to operate according to at least a transmit path linearization mode, and
wherein in the transmit path linearization mode,
i) one or more transmit paths of the switchable transmit and receive RF processing paths are each coupled to the respective element of the antenna array, and
ii) the switchable elements couple a portion of the RF signal through each of the one or more transmit paths to the one or more RF combiners to obtain a combined RF signal that is configured to be used by a controller for linearization of the one or more transmit paths.
