Patent ID: 8014728

Claim:
A method for calibrating a transmitter of a wireless device comprising: based upon an operational value of the wireless device, initiating transmitter calibration operations; performing the calibration operations 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: applying respective calibration settings: during the first interval portions applying substantially fixed first current input to at least one gain adjustable element of the RF circuitry; during the second interval portions apply varying current input to the at least one gain adjustable element of the RF circuitry; and measuring output levels of the RF circuitry over the calibration time period; and based upon the calibration operations, selecting operational calibration settings for baseband processing circuitry and/or signal path components of the transmitter.
