Abstract:
An RF front-end includes a transmit adjust module, a PA module, an antenna coupling circuit, a LNA module, and a receive adjust module. The transmit adjust module adjusts coordinates of up-converted analog signals when in a first transmit mode and adjusts coordinates of a plurality of up-converted analog signals when in a second transmit mode to produce to produce multiple adjusted up-converted signals and a plurality of adjusted up-converted signals, respectively, which are subsequently amplified by the PA module. The antenna coupling circuit provides the multiple or the plurality of outbound RF signals to at least some of a plurality of antennas depending on the transmit mode and provides multiple or a plurality of inbound RF signals at least some of the plurality of antennas to the LNA module based on a receive mode. The receive adjust module adjusts coordinates of the multiple or plurality of amplified inbound RF signals based on the receive mode.
