A planar dual mode filter has one or more resonators with L-shaped sections that are oriented back to back to one another. The filter can be constructed by adjusting the size of a gap between the back to back sections and adjusting the offset distance between adjacent sections. Further, coupling between adjacent resonators can be controlled by adjusting a distance between the adjacent resonators. The filters can be co-planar, stripline, suspended microstripline or microstripline. The filters have a film on a substrate with a ground plane. The film can be gold, silver or copper or it can be a ceramic material that becomes superconductive at cryogenic temperatures.
Filtre bimode planaire comprenant un ou plusieurs résonateurs munis de sections en L orientées dos à dos. Le filtre peut être construit en réglant l'écart entre les sections dos à dos et le décalage entre les sections contiguës. Le couplage entre les résonateurs contigus peut être contrôlé en réglant la distance entre ces résonateurs. Les filtres peuvent être coplanaires, en ligne triplaque, en ligne microruban suspendue ou non. Ils comprennent un ruban appliqué sur un substrat à plan de masse. Ce ruban peut être en or, en argent, en cuivre ou en un matériau céramique qui devient supraconducteur sous des températures cryogéniques.
