1. A mobile device comprising:
a baseband processor configured to generate a transmit signal, the baseband processor operable to provide digital pre-distortion to the transmit signal;
a transceiver configured to generate a radio frequency input signal based on the transmit signal;
a front end system including a plurality of transmit signal paths operable to process the radio frequency input signal to generate a plurality of radio frequency output signals, the plurality of transmit signal paths including a first transmit signal path configured to process the radio frequency input signal to generate a first radio frequency output signal of the plurality of radio frequency output signals, the front end system configured to provide analog pre-distortion to each of the plurality of transmit signal paths including the first transmit signal path, the analog pre-distortion operable to compensate for differences in distortion responses amongst the plurality of transmit signal paths, the differences in distortion responses including at least one of phase distortion or gain distortion; and
a first antenna configured to transmit the first radio frequency output signal.
