Enhancing the inefficiency of an RF power amp: The envelope tracking (ET) system

In this EDN article Steve Taranovich explores the envelope tracking system as a potential solution to the notoriously inefficient wideband power amplifiers (PAs) used I wireless telecom and other base station transmitters. An ET solution implementing high speed eGaN FETs in a multi-phase buck converter is explored.
