Abstract

This paper consists in the analysis and simulation of two topologies of high efficiency power amplifier (HPA) in the context of the cognitive multi-radio architecture. More precisely, the goal is to study the possibility of front-end radio standards flexibility using a class E HPA. Two main topologies are studied, serial and parallel, and simulations under ADS software are performed in order to validate the proposed tuning of the HPA. Results encourage possibilities of providing efficient and constant power amplification from almost 1 to 5 GHz.
