A Saturated Doherty Power Amplifier Based On Saturated Amplifier

, 2010
A saturated Doherty power amplifier (PA) based on the saturated PA tuned by the self-generated harmonic currents is presented. When driven with mobileWiMAX 1FA signal, this Doherty PA demonstrates high efficiency performance (average 57%) over the WiMAX ...
