Abstract

Et dobbeltmodusfilter som består av en ringresonator (1) realisert ved hjelp av mikro- båndlederteknikk, blir avstemt med hensyn til sin båndbredde ved at ledermaterial fjernes (1.1, 1.2, 1.3, 1.4, 2.1, 2.2, 2.3, 2.4) på et eller flere steder (x) på ringresonatoren (1) hvor den første av ringresonatorens to modi har sin største strømverdi og på et eller flere steder (o) på ringresonatoren hvor den andre modus har sin største strømverdi.
