Abstract

　特性劣化を抑圧しつつ、高効率で広帯域信号を増幅する電力増幅器。この電力増幅器において、信号生成器（１２０）は、最終段増幅器（１４０）に入力される入力信号の立ち上がりタイミングに比べ、立ち上がりタイミングが所定時間だけ早い第１信号を、エンベロープ信号に基づいて生成する。電源変調器（１３０）は、第１信号に基づいて、最終段増幅器（１４０）に印加する電源電圧信号を生成し、最終段増幅器（１４０）の電源電圧端子に印加する。これにより、電源変調器（１３０）の通過帯域が入力信号の帯域より狭い場合であっても、電源変調器（１３０）は、入力信号の立ち上がりに追従した電源電圧を最終段増幅器（１４０）の電源電圧端子に印加することができ、電源変調器（１３０）に高効率なパルス変調方式を用いて、電力増幅器全体として高効率を維持しつつ、特性劣化を抑えながら広帯域信号を増幅することができる。
