Abstract:
1. A method for calibrating a transceiver, the method comprising: activating one of a plurality of calibration paths in the transceiver; providing, from a baseband processor, a calibration signal via an input connection of a transmitter path of the transceiver, the transmitter path including at least one baseband analog filter; obtaining, by the baseband processor, the calibration signal from an output connection of a receiver path of the transceiver; and controlling, by the baseband processor, a characteristic of at least one digital-to-analog converter (DAC) coupled to the at least one baseband analog filter to adjust the at least one baseband analog filter based on the calibration signal, wherein transceiver components in the activated calibration path are powered up and transceiver components not in the activated calibration path are powered down when obtaining the calibration signal.
