The Promise of Load Modulation and Doherty Power Amplifiers

This talk shall explicitly address efficiency enhancement in PAs using load modulation and Doherty PAs. The concept of load modulation shall be introduced using theory and examples, and the specific case of load modulation using a Doherty PA architecture shall be detailed in this talk. This tutorial will introduce the challenges with integrating load modulation within an IC/MMIC, and recapture several of the latest methods and propose techniques for successfully realizing integrated load-modulated PAs.
