Power amplification apparatus of portable terminal

The power amplifier in the invention relates to a mobile phone device, which efficiency and strip-shaped of the power amplifier. The power amplifier is fixed to the following way which the characteristic, controlling the output voltage of peak amplifier, wherein according to an output unit output power's size, the low power output mode, a power amplifier operations in Holty manner; and a lower high power output mode, the output voltage of peak amplifier can be added to satisfying power amplifier misalignment operation requirement of. Additionally, wherein without controlling the output voltage of peak amplifier, capable of the power amplifier with a simple in. , Wherein the size of the power amplifier is of small, wherein reduced the charging of power amplifier.
