Abstract

　広ダイナミックレンジ信号についても高効率かつ低歪で増幅することができる送信装置。この装置において、エンベロープ信号の信号レベルに応じて、エンベロープ信号を、基準レベル以上の信号と、基準レベル未満の信号とに分離するレベル分離器と、基準レベル以上の信号をパルス幅変調して、第１のパルス幅変調信号を形成する第１のパルス幅変調器と、基準レベル未満の信号をパルス幅変調して、第２のパルス幅変調信号を形成する第２のパルス幅変調器と、第１の印加電圧が入力され、第１の印加電圧を第１のパルス幅変調信号によってスイッチングして出力する第１のトランジスタと、第１の印加電圧よりも小さい第２の印加電圧が入力され、第２の印加電圧を第２のパルス幅変調信号によってスイッチングして出力する第２のトランジスタと、第１と第２のトランジスタの出力信号との合成信号を平滑化して、電力増幅器の電源端子に出力する平滑回路と、を有する。
