Abstract

In this contribution, an innovative design solution to realize small size Doherty power amplifier is presented. The idea consists in the realization of a unique output matching network for both carrier and peaking devices without losing the Doherty behavior. Experimental results performed on uneven Doherty amplifier using GaN HEMT device is given to demonstrate the proposed approach. © 2008 Wiley Periodicals, Inc.
