Abstract

Procédé pour la fabrication d'un filtre de micro-onde muni d'une sphérule de YIG et d'une source émettant un champ magnétique de prépolorisation dont la fréquence de résonance est fonction de la température d'une façon définie d'avance. En respectant une orientation définie d'avance, on amène dans le filtre une sphérule de YIG servant de référence, et du fait de modifier l'intensité du champ magnétique, on porte la fréquence de résonance à une valeur définie d'avance. Ensuite, on amène dans le filtre une autre sphérye de YJG, que l'on fait tourner jusqu'à constater l'égalité de fréquence de résonance et de fréquence définie d'avance, après quoi ladite autre sphérule est bloquée. Application aux récepteurs de télévision.
