Impact of Bias Schemes on Doherty Power Amplifiers [PDF]
2005 IEEE International Symposium on Circuits and Systems, 2005 This paper investigates the performance of a 2.4GHz CMOS two-way Doherty power amplifier with the different bias schemes for the auxiliary power device. For the conventional bias schemes, there are design tradeoffs in terms of power gain, gain flatness, P/sub 1dB/, power-added efficiency, and third order harmonics.

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.
