Title (EN) APPARATUS FOR REMOVING DISTORTIONS CREATED BY AN AMPLIFIER
(FR) ELIMINATION DES DISTORSIONS PROVOQUEES PAR UN AMPLIFICATEUR
Abstract: front page image
(EN)A power amplifier has a non-linear low power pre-distortion amplifier (112) for transforming a carrier signal (111) to a pre-distorted signal (113) having a carrier component with out-of-phase non-linear distortions, and a non-linear power amplifier (114) having non-linear characteristics similar to a portion of the non-linear low power pre-distortion amplifier for generating from the pre-distorted signal a transmission signal (115) having an amplified carrier component with substantially diminished non-linear distortions.
(FR)Cette invention concerne un amplificateur de puissance à pré-distorsion, basse puissance, non linéaire (112) permettant de transformer un signal porteur (111) en un signal à pré-distorsion (113) dont la composante porteuse présente des distorsions non linéaires déphasées, et un amplificateur de puissance non linéaire présentant des caractéristiques de non linéarité analogues à une partie de l'amplificateur à pré-distorsion, basse puissance, non linéaire, capable de générer à partir du signal à pré-distorsion un signal de transmission (115) assorti d'une composante porteuse amplifiée présentant des distorsions non linéaires sensiblement réduites.
