Abstract
This article introduces a gate bias control scheme for Doherty amplifiers, based on the measured gate‐voltage to drain‐current transfer characteristics of the FETs used, and their ideal fundamental output currents. An amplifier was realized at 800 MHz, and achieved over 35% drain efficiency from 8–14 dBm input power. © 2009 Wiley Periodicals, Inc.
