Abstract

SYSTEME D'ALIMENTATION POUR UN AMPLIFICATEUR CONSTITUE PAR UNE CASCADE D'AMPLIFICATEURS SELECTIFS A CONTRE-REACTION ELEMENTAIRES. L'ALIMENTATION DE PUISSANCE EST FOURNIE A CHACUN DES ELEMENTS ACTIFS A1, A2, A3 PAR L'INTERMEDIAIRE DE MOYENS D'ACCOUPLEMENT MN1, MN2, MN3 ET DE MOYENS DE COUPLAGE REACTIF LN1, LN2, LN3 MONTES EN SERIE, L'ALIMENTATION ETANT CONNECTEE EN N'IMPORTE QUEL POINT DU MONTAGE EN SERIE PAR L'INTERMEDIAIRE DE MOYENS DE DECOUPLEMENT LN4. AVEC CE SYSTEME, ON NE RENCONTRE AUCUN PROBLEME DE FILTRATION ENTRE LES ETAGES POUR EVITER LES COUPLAGES DE PARASITES.
