Popis: A Doherty amplifier's theoretical gain and efficiency characteristics significantly exceed those achieved by practical simulations and implementations. Analysis and simulation demonstrates that the FET gate voltage to drain current transfer characteristic has a significant detrimental effect on these characteristics, indicating it is the major factor in the difference between ideal and practical results. © Wiley Periodicals, Inc.
