Abstract

L'invention concerne un dispositif d'amplification qui amplifie les signaux d'entrée injectés depuis une borne d'entrée, délivre ceux-ci depuis une borne de sortie et comprend : un premier amplificateur qui amplifie les signaux d'entrée ; un deuxième amplificateur qui amplifie une composante de crête des signaux d'entrée ; une première unité de réglage de phase connectée à la sortie du premier amplificateur, laquelle décale la phase des signaux amplifiés par le premier amplificateur et délivre ceux-ci, et laquelle est capable de régler le niveau de déphasage ; et une deuxième unité de réglage de phase qui décale la phase des signaux délivrés par la première unité de réglage de phase et les signaux délivrés par le deuxième amplificateur, délivre ceux-ci à la borne de sortie et est capable de régler le niveau de déphasage.
