A system and method of optimizing the output power of a power amplifier to maintain satisfactory RF response under varying power amplifier operating conditions. The operating conditions include operating temperature, supply voltage, and operating frequency. Existing sensors monitor the aforementioned operating conditions. An application within the wireless device containing the power amplifier continuously or periodically logs the current operating conditions and finds them in a look-up table stored internally. The look-up table is comprised of empirically derived maximum sustainable power output levels for each operating condition. Once the current operating conditions are matched to a set in the table, current power amplifier power output is reset, if necessary, to the maximum sustainable power output defined in the table.
