Many electronic applications have a need for linear power amplifiers. In the past, power amplifier linearity was often achieved by performing a factory calibration procedure to develop pre-emphasis compensation for the power amplifier to linearize the gain thereof. The compensation information would then be stored within the device carrying the power amplifier for use throughout the life of the amplifier. This factory calibration procedure can be complex and costly to perform for each item in a production line. In addition, this calibration technique only compensates for distortion in the power amplifier under the conditions that exist at the time the calibration is performed and does not provide compensation for effects such as gain variation as a function of junction temperature, gain variation as a function of component aging, non-linearity effects associated with the use of different modulation techniques, and/or other gain variations that might occur during component operation. There is a need for power amplifier linearization techniques that are capable of adapting to changing conditions associated with an amplifier.
