基于混合结构与优化控制策略的多模块并联兆赫兹功率放大器

Megahertz power amplifiers typically modulate power by paralleled-architectures and outphasing methods. However, when power drops in a large ratio, the effective admittances of modules are always not within the high-efficiency range. This article optimizes four-paralleled-module system through two operation modes: four modules turn-on at high power and two modules turn-on at low power to reduce th...
