摘要：
The invention intends to supply a power amplifier enable to correct a distortion correctly by linealizer corresponding to each amplifier if plural amplifiers are used at any operation points. A power amplifier according to the invention includes a plurality of amplifiers 32 and 34 connected with multiple stages and a plurality of linealizers 10 and 20 connected with multiple stages and correcting non-linear distortions of the amplifiers 32 and 34. In the invention, a distortion in the amplifier of a former stage is corrected by the linealizer of a later stage.
