Abstract

UN MONTAGE POUR UNE COMPENSATION DE LA DERIVE DE FREQUENCE D'UNE DIODE D'ACCORD DANS DES CIRCUITS HF ACCORDABLES, QUI COMPORTE UN DIVISEUR DE TENSION DEPENDANT DE LA TEMPERATURE, EST CONNU. CE MONTAGE A L'INCONVENIENT D'ETRE CONNECTE A LA TENSION D'ACCORD ET DE LA CHARGER D'UN COURANT TRES IMPORTANT. CECI N'EST PLUS ADMISSIBLE LORSQU'ON UTILISE DES ELEMENTS A CIRCUIT INTEGRE. PAR CONSEQUENT, IL EST PROPOSE DE CONNECTER LEDIT DIVISEUR DE TENSION DEPENDANT DE LA TEMPERATURE A UNE SOURCE DE TENSION DE SERVICE INDEPENDANTE. LA MISE EN CHARGE DE LA TENSION D'ACCORD EST AINSI EVITEE ET UNE MEILLEURE COMPENSATION DE FREQUENCE EST POSSIBLE. APPLICATION: AUX CIRCUITS HF DE TELEVISION.
