摘要： The present invention discloses a high efficiency power amplifier comprising: an input matching unit for matching input signal; a first amplifying means for amplifying the signal outputted from the input matching unit; a second amplifying means for amplifying the signal outputted from the input matching unit; an output matching unit for performing an impedance matching the amplified signal from the first and second amplifying means and outputting the matched signal through an output terminal; a first power control path for electrically connecting between the input matching unit and the output matching unit and including the first amplifying means; a second power control path for electrically connecting between the input matching unit and the output matching unit and including the second amplifying means; a bypass path for electrically connecting between the input matching unit and the output matching unit; and a control circuit unit for selectively outputting the predetermined path control signals to the first and second amplifying means on the basis of an antennal output signal outputted and applied from a predetermined control module like an MSM (Mobile Station Modem).
