Calibrated power amplifier module

A power amplifier module comprising:

• a. an input for receiving a signal having an input power level;
• b. at least one power amplifier coupled to the input to increase the input power level of the signal to an output power level;
• c. a power detector in signal communication with the at least one power amplifier to measure the output power level;
• d. a power controller for comparing the output power level to a target power level and producing a control signal for the power amplifier based on the comparison;
• and
• e. a power calibrator coupled to the power controller for determining a correction based on a set of factors;
• wherein the power detector is a logarithmic amplifier.
