Abstract
A power amplifier module includes an input for receiving a signal having an input power level, at least one power amplifier coupled to the input to increase the input power level of the signal to an output power level and a power calibration and control module coupled to the power amplifier for measuring the output power level and correcting the output power level measurement based on a set of factors. The power calibration and control module further controls the at least one power amplifier to produce an output power level equivalent to a target power level. The power calibration and control module may include a power detector, a power calibrator and a power controller. The power amplifier module may further include a power set interface coupled to the power calibration and control module for providing the target power level.
