Abstract

L'invention concerne les amplificateurs haute fréquence. Un amplificateur interférométrique décompose le signal d'entrée selon les projections de ce signal sur deux signaux de référence orthogonaux, l'un des signaux de référence pouvant suivre la fréquence instantanée du signal d'entrée. Des modulateurs de phase 41, 42 décomposent en outre les signaux obtenus en paires de signaux à amplitude constante et phase variable qui sont amplifiés par les amplificateurs 51-54, puis sont combinés pour former un signal qui est une version amplifiée du signal d'entrée. Application aux amplificateurs linéaires de forte puissance.
