摘要：
A power amplifier is provided which is capable of performing efficient amplification in a wider transmission signal power range than conventional power amplifiers. The power amplifier for amplifying and outputting an input signal includes first to N-th amplifiers (N is an integer of two or more) which are cascaded. A Doherty amplifier is used in circuit configuration of each of the first to N-th amplifiers. At least one of the first to (N-1)-th amplifiers has a different power ratio from that of the N-th amplifier.
