Zusammenfassung:	An analog predistortion linearizer system with dynamic frequency compensation for automatically adjusting predistortion characteristics based on a detected frequency includes a frequency detector configured to generate at least one frequency detection signal in response to receiving an amplifier drive signal, the frequency detection signal including a frequency indicator that indicates the frequency of the amplifier drive signal. Moreover, the system also includes a controller communicatively coupled to the frequency detector and configured to generate a predistorter control signal in response to receiving the frequency detection signal from the frequency detector, and a predistorter communicatively coupled to i) the frequency detector and ii) the controller, the predistorter configured to generate a predistorted amplifier drive signal based on at least the predistorter control signal.
