A high efficiency EER-based transmitter

The efficiency and linearity of a Power Amplifier (PA) is critical for a transmitter in most wireless communication systems. A lot of research has been done to improve these two parameters in transmitters. This project focuses on the highly efficient Radio Frequency Power Amplifier (RF-PA) implementation using Envelop Elimination and Restoration (EER) architecture with dynamic drain voltage supplier. The transmitter has been designed and implemented the entire transmitter in MATLAB/SIMULINK. Each individual component is implemented to include envelop and phase extraction, digitally controlled DC-DC converter, E-class power amplifier and phase shifter. In this report, simulation results have been presented along with an analysis of results, showing that limitations in the performance of some of the components affect the overall system performance.
