Systems and methods for a predistortion linearizer with frequency compensation

A processor-executable method for automatically adjusting predistortion characteristics of a radio frequency signal comprising:

• receiving, via a frequency detector, the radio frequency signal;
• detecting, via the frequency detector, a frequency value in response to the receiving;
• generating, via the frequency detector, at least one frequency detection signal in response to detecting, said at least one frequency detection signal comprising an analog signal or a digital signal;
• generating, via a controller, a predistortion control signal in response to the detected frequency value;
• and
• generating, via an analog predistorter, a predistorted amplifier drive signal to the radio frequency signal such that the generated predistorted amplifier drive signal counteracts a gain amplitude and phase distortion of an amplifier when processing the radio frequency signal, wherein said controller comprises a circuit for processing the received analog signal and for generating a proper predistortion signal for the analog predistorter.

An analog predistortion linearizer apparatus with dynamic frequency compensation for automatically adjusting predistortion characteristics based on a detected frequency, the apparatus comprising:

• an analog predistorter for receiving a drive signal;
• a frequency detector communicatively coupled to the analog predistorter, wherein the analog predistorter communicates the received drive signal with the frequency detector;
• wherein the frequency detector generates a frequency detection signal in response to the received drive signal, the frequency detection signal including a frequency indicator that indicates a frequency of the drive signal, said at least one frequency detection signal comprising an analog signal or a digital signal;
• a controller communicatively coupled to the frequency detector and the analog predistorter, said controller generating a predistorter control signal in response to receiving the at least one frequency detection signal from the frequency detector;
• and
• wherein the analog predistorter generates a predistorted drive signal based on the predistorter control signal, and wherein said controller processes the received analog signal and for generating a proper predistortion signal for the analog predistorter.
