Title (EN) NOTCH FILTER AND EXTRACTOR ARRANGEMENT COMPRISING IT
(FR) FILTRE COUPE-BANDE ET AGENCEMENT D'EXTRACTEUR COMPRENANT LE FILTRE COUPE-BANDE
Abstract: front page image
(EN)In a notch filter in a ladder-type arrangement, spurious modes can be suppressed and linearity can be improved by impedance elements designed as resonators (ZS, ZP) being bridged in parallel by one capacitor each (ZS with CESP, ZP with CEPP) or connected in series to such a capacitor (ZS with CESS, ZP with CEPS).
(FR)Selon la présente invention, dans un filtre coupe-bande d'un agencement de type en échelle, des modes parasites peuvent être supprimés et la linéarité peut être améliorée au moyen d'éléments d'impédance conçus comme des résonateurs (ZS, ZP) étant chacun ponté en parallèle par un condensateur (ZS à CESP, ZP à CEPP) ou connecté en série à un tel condensateur (ZS à CESS, ZP à CEPS).
