Optimisation des performances des terminaux de communication par répartition maîtrisée de la fonction de filtrage dans la chaîne d'émission HF

Abstract : Due to the increasing number of user applications available on mobile phones, raising requirements on the radio-frequency components and particularly on the filters are a consequence of the multistandard characteristics and the reconfigurable RF systems. In this work, we propose a solution which consists in distributing the filtering function on the entire RF transmitter. Thus, while maintaining its basic functionality, each component (filter, diplexer, amplifier, antenna) creates additional filtering so that the filtering capabilities of the global transmitter are satisfactory for the different standard requirements. This dissertation presents a first study on this subject. It demonstrates the feasibility of the filtering distribution concept, showing several multi-functional architectures such as filtering-amplifiers, filtering-power-dividers, filtering-antennas...
