Abstract

DANS UN ETAGE AMPLIFICATEUR A TRANSISTOR POLARISE EN CLASSE A, LA NON-LINEARITE DE LA CARACTERISTIQUE DE TRANSFERT IF (I) DU TRANSISTOR OBLIGE A MAINTENIR LE NIVEAU DE SORTIE DE L'ETAGE EN DESSOUS DE LA ZONE OU ELLE SE MANIFESTE. LE DISPOSITIF DE CORRECTION SELON L'INVENTION COMPREND AU MOINS UN COMPOSANT ELECTRONIQUE NON LINEAIRE INSERE DANS LE CIRCUIT BASE-EMETTEUR DU TRANSISTOR DE L'ETAGE ET RELIE A UN CIRCUIT DE POLARISATION ANNEXE. UN REGLAGE APPROPRIE DU POINT DE FONCTIONNEMENT DE CE COMPOSANT NON LINEAIRE ASSURE UNE COMPENSATION EXACTE DES DEFAUTS DE LINEARITE DU TRANSISTOR ET SUPPRIME LES EFFETS DE CES DEFAUTS (RAIES D'INTERMODULATION, DISTORSION). CE COMPOSANT EST PAR EXEMPLE UNE DIODE OU UN TRANSISTOR A EFFET DE CHAMP. APPLICATION: AMPLIFICATEURS CLASSE A UTILISES EN TELEDISTRIBUTION DANS LES INSTALLATIONS D'ANTENNES.
