Abstract
A transceiver has a digital signal processor which can insert calibration signals of known level and frequency into transmitters for calibration and correction of transmitter parameters. An output of the calibrated and corrected transmitter is subsequently coupled into a calibration mixer along with a mixing signal (e.g., from a local oscillator generator. The outputs of the calibration mixer have known levels and frequencies and are inserted into receivers for calibration and correction of receiver parameters.
