Abstract
L'invention concerne un transformateur hybride. Elle se rapporte à un transformateur dans lequel un substrat céramique 11 porte des conducteurs métallises 12, disposés sensiblement radialement, et un noyau 19 de ferrite est placé sur les conducteurs 12. Des fils métalliques 24 forment des boucles conductrices entre une extrémité interne d'un conducteur 12 adjacent au précédent. Application à la réalisation de circuits à transformateur comprenant des paillettes de circuit intégré.
