1. Radio frequency (RF) power amplifier (PA) circuitry comprising:

  • an amplifier stage configured to receive and amplify an RF input signal to provide an RF output signal;

    gain compensation circuitry coupled in parallel with the amplifier stage and configured to receive the RF input signal and provide a gain compensation signal, wherein the gain compensation signal is configured to linearize at least a portion of a gain response of the amplifier stage; and

    an adder coupled between an output of the amplifier stage and the gain compensation circuitry and configured to receive and add the RF output signal and the gain compensation signal to provide a linearized RF output signal.
