Abstract

En bredbåndsimpedanstilpasningskrets som anvender høypass- og lavpassfilterseksjoner, som er vekselvis kaskadekoblet sammen for å gi betydelig bredere båndtilpasning enn to høypassfilterseksjoner eller to lavpassfilterseksjoner. Ved å la høypassfilterseksjonene veksle med lavpassfilterseksjonene, kreves betydelig færre elementer for et gitt resultat enn ikkevekslende, tidligere kjente, kaskadekoblede filterseksjoner. Følgelig forbedrer de vekslende filterseksjonene i henhold til den foreliggende oppfinnelsen, i vesentlig grad returtapet ved økte båndbredder.
