ABSTRACT:
A radio frequency transceiver for off-line transmit and receive calibrations includes: a transmit pre-distortion module configured to receive a transmit calibration signal during a transmit calibration mode, a transmit communication signal during a transmit communication operation mode, and one or more transmit calibration adjustment signals; a transmit channel frequency converter; and a transmit calibration module configured to provide the one or more transmit calibration adjustment signals and the transmit calibration signal to the transmit pre-distortion module. It may also include a receive channel frequency converter; a receive pre-distortion module configured to receive a receive calibration signal during the receive calibration mode, a receive communication signal during a receive communication operation mode, and one or more receive calibration adjustment signals; and a receive calibration module configured to provide the one or more receive calibration adjustment signals to the receive pre-distortion module and a receive calibration signal to the transmit pre-distortion module.
