Predistortion Calibration In A Transceiver Assembly

摘要

Systems and methods are provided for calibrating a digital predistorter in an integrated transceiver circuit. A digital transmitter path provides a signal from a digital input. The transmitter path includes a digital predistorter that predistorts the digital input to mitigate nonlinearities associated with a power amplifier. The integrated transceiver circuit further includes a receiver path associated with the digital transmitter path. A coupling element provides the signal from the transmitter path to the receiver path. A signal evaluator determines values for at least one parameter associated with the digital predistorter based on the signal.
