The aim of this thesis work was to design a power amplifier for WiMAX applications at 3.5GHz based on cheap Si-LDMOS technology and to analyze the behavior of the design regarding nonlinear distortions and memory effects. A MW6S004NT1 Si-LDMOS RF high power transistor, from Freescale, with an ADS MET model was used in the process. This transistor is specified for Class A-AB base station applica...

In this paper, an lateral diffused metal–oxide– semiconductor-based very high-frequency class-E power amplifier has been investigated theoretically and experimentally. Simulations were verified by amplifier measurements and a record-high class-E output power was obtained at 144 MHz, whic is in excellent agreement with simulations. The key of the results is the use of efficient device models, si...

The low efficiency of existing power amplifiers (PAs) is causing excessive energy consumption in wireless systems. Improving the PA efficiency is therefore of great environmental and economical importance. This thesis address a wide range of advanced PA design methods and novel PA architectures that all contribute to significantly improve the efficiency of PAs for wireless applications. The fir...
