This project deals with modern efficient transmitter architectures based on digitally assisted PA subsystem architectures such as Doherty, envelope tracking (ET), outphasing and all-digital. The goal is to study the main operation concepts and highlight the current technology performance levels and limitations both in terms of linearity and efficiency when handling ultra-wide bandwidth signals featuring high peak-to-average power ratio (PAPR). The state-of-the-art review will also include industrial developments for each of the technologies and analyze the advantages, disadvantages and suitability according to the target application scenario defined in the project.
