The PHD work proposed in this WP consists in the study of a design criterion of the type C/(N+I) versus Pdc/N and to come to comparative results for different PA architectures. (Conventional PA architecture with harmonic tuning , and Envelope tracking PA for example). An important attention will be paid to experiments in order to investigate potential impact of dispersive effects that are difficult to analyse theoretically when modulated signal are used. Preliminary investigations for switched mode power amplifiers will be carried out.
