A method of producing filters using lower unloaded Q factor components than filters with the same performance characteristics but requiring higher unloaded Q factor components. The method comprises the steps of defining a desired filter characteristic and applying an algorithm which provides a filter having infinite Q factor elements and having a theoretical characteristic corresponding to the desired characteristic transformed to compensate for the difference between finite Q factor and infinite Q factor elements.
Procédé de fabrication de filtres au moyen de composantes non chargées de facteur Q inférieures à celles de filtres possédant les mêmes caractéristiques d'efficacité mais nécessitant des composantes non chargées de facteur Q plus élevées. Ce procédé consiste à définir une caractéristique souhaitée du filtre et à appliquer un algorithme permettant d'obtenir un filtre possédant des éléments de facteur Q infinis, ainsi qu'une caractéristique théorique correspondant à la caractéristique souhaitée transformée afin d'équilibrer la différence entre des éléments finis et infinis de facteur Q.
