    • A power amplification apparatus includes, between a first amplification element for amplifying an input signal and a first output terminal, a second amplification element for further amplifying the input signal amplified in the first amplification element to output to the first output terminal, and a first switch element for controlling the second amplification element to be stop condition. Further, between the first amplification element and a second output terminal, a second switch circuit for controlling the supply of an output from the first amplification element to the second output terminal is provided. When outputting a medium power, the operation efficiency of the power amplification apparatus is improved by reducing a power consumption. Thereby, a total operation efficiency of the power amplification apparatus which outputs either the input signal amplified to a large power or the input signal amplified to a medium power by switching is improved.
    • 功率放大装置包括用于放大输入信号的第一放大元件和第一输出端之间的第二放大元件,用于进一步放大在第一放大元件中放大的输出信号以输出到第一输出端;第一开关 元件,用于控制第二放大元件为停止状态。 此外,在第一放大元件和第二输出端子之间,提供用于控制从第一放大元件输出到第二输出端子的输出的第二开关电路。 当输出中等功率时,通过降低功耗来提高功率放大装置的操作效率。 从而,通过切换输出被放大到大功率的输入信号或输入信号被放大到中等功率的功率放大装置的总体操作效率得到改善。
