Abstract :
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 output power of 40.7 dBm in correspondence of 56% drain efficiency.
