1. A system for affecting operation of an envelope tracking (ET) amplifier, comprising:

  • an ET amplifier configured to receive an RF input signal and generate therefrom, an RF output signal based on a response of the ET amplifier; and

    a set of operating parameters defining the response of the ET amplifier;

    a control circuit adapted to detect an envelope of the RF input signal and generate based on said envelope signal a set of input-control signals that is provided to the ET amplifier for affecting the response according to the set of operating parameters.
