Abstract:
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; b) a power-sensing circuit adapted to receive the amplified radio frequency signal and to output the power-sensing control signal; c) a control logic that receives and processes the power-sensing control signal, and outputs a processed power-sensing control signal in response to a quality or a magnitude of the amplified radio frequency signal; d) a mode control circuit coupled to the radio frequency power amplifier to control power of the radio frequency power amplifier; e) an electronic circuit including the radio frequency power amplifier, the power-sensing circuit and the control logic, said electronic circuit having an electrically conductive base; and f) a multi-layer three dimensional substrate having a conductive layer adapted to bond with the electrically conductive base.
