Abstract
Transmitter calibration of a wireless device is initiated based upon an operational value of the wireless device. The calibration operations are performed over a plurality of calibration time periods, each calibration time period divided into a plurality of first interval portions interspersed with a plurality of second interval portions, for each calibration time period of the plurality of calibration time periods, respective calibration settings are applied. During the first interval portions substantially fixed first current input is applied to at least one gain adjustable element of the RF circuitry. During the second interval portions, varying current input is applied to the at least one gain adjustable element of the RF circuitry. Output levels of the RF circuitry are measured over the calibration time period. Operational calibration settings for the baseband processing circuitry and analog signal path components of the transmitter are selected based upon the calibration operations.
