Abstract:
1. A system comprising: a power amplifier having an output signal and a drain current; a power amplifier calibration module configured to determine an optimized quiescent drain current value for the drain current while the power amplifier is operating under an operational parameter, and determine a set of calibrated drain current values for the drain current, the set of calibrated drain current values being calibrated for a set of power levels for the output signal while the power amplifier is operating under the operational parameter; a storage module configured to store the optimized quiescent drain current value and the set of calibrated drain current values as saved drain current data; and a power amplifier operation module configured to compare the drain current to a particular drain current value in the saved drain current data, determine whether the comparison satisfies a condition, and adjust the drain current based on the particular drain current value if the condition is determined to be satisfied.
