Abstract
A method for calibrating a transceiver includes selecting one of a plurality of available calibration paths on the transceiver to be active. The transceiver includes a transmitter and a receiver. The selected one of the plurality of available calibration paths couples the transmitter to the receiver through a circuit that is external to the transceiver. A calibration signal may be provided to enable calibration of the transceiver via the selected one of the plurality of available calibration paths. The calibration signal may be received after it has passed through the selected one of the plurality of calibration paths. Characteristics of the transceiver may be measured using the received calibration signal.
