摘要:
A high-frequency power amplifier comprising: a plurality of power amplifiers arranged in parallel; an inductance element inserted in series in an input signal line of said each power amplifier; an input matching circuit for performing matching of inputs of a parallel connection which connected each series connection of said power amplifier and said inductance element in parallel; an output matching circuit for performing matching of outputs of the parallel connection; and a control unit for controlling said power amplifiers in such a manner that one of said power amplifiers is always brought to an operation condition and the remainder of said power amplifiers are brought to an operation or non-operation condition.
