Abstract

A CMOS implementation of a Class E power amplifier for wireless communications which operates in the GHz region is reported. The concept of mode-locking is introduced in which the amplifier acts as an oscillator whose output is forced to run at the input frequency. A prototype was built, which delivered over 1W of output power with 48% power added efficiency, centred at 1.9GHz using a 2V supply.

一种用于无线通信的1.9GHz 1W CMOS E类功率放大器

本文报道了一种工作在GHz频段的用于无线通信的E类功率放大器的CMOS实现。锁模的概念被引入，其中放大器作为一个振荡器，其输出被强制运行在输入频率。原型机的输出功率超过1W，功率增加48%，集中在1.9GHz，使用2V电源。
