Abstract
A radio frequency (RF) transceiver includes a transmitter portion configured to transmit RF signals at an output of a power amplifier (PA). A receiver portion has an input coupled to the output of the PA. The receiver portion includes a switch coupled to feedback first baseband signals to the transmitter portion during a feedback mode. The first baseband signals are based on the first RF signals received at the input of the receiver portion. A pre-distortion processing unit is coupled to receive the first baseband signals. In turn, the distortion processing unit provides pre-distortion feedback signals to the transmitter portion.
