摘要： There is provided a power amplifier capable of increasing linear output power and efficiency without sacrificing an overall gain by employing a vector modulation function in a driving stage, with no separate vector modulator. The power amplifier includes a driving stage performing vector-modulation on an input RF signal to provide an I channel signal and a Q channel signal having different phases and amplifying the I channel signal and the Q channel signal to set gains; and a power stage amplifying power levels of the signals amplified by the driving stage.
