This paper presents the design of a concurrent tri-band Doherty Power Amplifier (DPA) for 1.84 GHz, 2.14 GHz and 2.65 GHz frequency bands. The frequency response around each operating band is maximally flattened adopting a new design strategy. The DPA is based on hybrid technology using two 8 W GaN HEMT as active devices. The results show a peak of drain efficiency higher than 60 % in each operating...
In this contribution, the analysis on high frequency Class E design approach is presented. Starting from the classical theory, a numerical analysis is performed to extend class E feasibility at higher frequencies. The design of hybrid Class-E amplifier in LDMOS technology for UMTS base-station applications will be presented, in order to validate the theoretical results. The simulated PA reaches an...
