Abstract
A packet-based wireless transceiver that transmits and receives data packets includes a transceiver component having an adjustable performance parameter. A calibration circuit adjusts the performance parameter of the transceiver component at times synchronized with the data packets. A calibration signal generator generates calibration signals based on the performance parameter and outputs the calibration signals to the transceiver component. A comparator receives the outputs of the transceiver component and generates a difference signal. A calibration adjustment circuit communicates with the calibration signal generator and the comparator and adjusts the performance parameter to reduce the difference signal. Alternately, a reference signal generator generates a reference signal. A comparator receives the reference signal and a second signal from the transceiver component and generates a difference signal. A calibration adjustment circuit adjusts the performance parameter of the transceiver to reduce the difference signal.
