3.0-3.6 GHz Wideband . over 46% Average Efficiency GaN Doherty Power Amplifier with Frequency Dependency Compensating Circuits

To realize the wideband DPA above 3GHz. the frequency dependency compensating circuit and the λ ۴ inverter incorporating parasitic elements inside package were proposed. The feasibility of the approach was verified by measurement results. and it achieved 45.9- 50.2 % drain efficiency with -50 dBc ACLR over the 3.0- 3.6 …
