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

  • a) a radio frequency power amplifier 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; and

    b) a power-sensing circuit adapted to receive the amplified radio frequency signal and to output the power-sensing control signal and a multi-layer three dimensional substrate having a conductive layer adapted to bond with an electrically conductive base;

    c) a radio frequency transceiver coupled to the radio frequency power amplifier; and

    d) a processor coupled to the radio frequency transceiver and to the vower sensing control signal.
