摘要：

Radio frequency spectrum is expensive and sophisticated modulation techniques, leading to wide, dynamic signals require linear amplification. The penalty for achieving linearity is efficiency. The challenge is therefore to develop power amplifiers which offer high linearity and high efficiency in the back-off. In this paper, the idea of Modified Doherty Amplifier ill is extended by using a push-pull class-B amplifier in place of class-AB amplifier and a complementary class-C amplifier in place of single ended. class-C amplifier to improve linearity and to provide high efficiency in back-off.
