摘要：
Provided is a low power consuming mixed mode amplifier. The power amplifier includes: a low output amplifier circuit generating a power amplified result having high efficiency in a low output mode the most frequently used; a high output amplifier circuit generating an amplified result of high linearity in a high output mode of a region consuming the most power; an amplifier controller selectively activating the low and high output amplifier circuits according to a power level of an input signal. The high and low output amplifier circuits have a predetermined gain difference.
