1. A power amplifier module for amplifying radio frequency signals, comprising:

  • a) first and second radio frequency power amplifiers each including one or more semiconductor transistors, adapted to receive an input radio frequency signal and a processed power-sensing control signal, and to output an amplified radio frequency signal;

    b) first and second power-sensing circuits each coupled to said first and second radio frequency power amplifiers and adapted to receive each amplified radio frequency signal and to output the power-sensing control signal; and

    c) control logic that receives and processes the power-sensing control signals, and outputs a processed power-sensing control signal in response to each quality or magnitude of each amplified radio frequency signal, wherein the quality or magnitude of the amplified radio frequency signal includes Error Vector Magnitude (EVM), Bit Error Rate (BER), or Packet Error Rate (PER).
