A METHOD FOR DESIGNING BROADBAND DOHERTY POWER AMPLIFIERS [PDF]
Progress In Electromagnetics Research, 2014 In this contribution, a design approach for the realization of broadband Doherty Power Ampliflers (DPAs) is proposed and demonstrated. The methodology is based on the exploitation of the wideband response of 2-sections branch-line couplers both as input splitter and output combiner of the DPA.
