Title (EN) FILTER BASED ON A COMBINED VIA STRUCTURE
(FR) FILTRE BASÉ SUR UNE STRUCTURE DE TROUS D'INTERCONNEXION COMBINÉS
Abstract:
(EN) A filter is provided with a planar transmission line and a combined via structure connected to (both) one ends of the planar transmission line. The planar transmission line and the combined via structure are disposed in a same multilayer board. The combined via structure comprises two working parts. The first working part comprises a segment of signal via and a plurality of segments of ground vias surrounding the signal via. The second working part comprises a segment of the same signal via, a plurality of segments of the same ground vias, smooth conductive plate and corrugated conductive plate. The smooth conductive plate and the corrugated conductive plate are connected to the signal via. The second working part comprises a segment of the same signal via, a plurality of segments of the same ground vias and corrugated conductive plate. The corrugated conductive plate is connected to the signal via.
(FR) Un filtre est pourvu d'une ligne de transmission plane et d'une structure de trous d'interconnexion combinés connectée aux (deux) extrémités de la ligne de transmission plane. La ligne de transmission plane et la structure de trous d'interconnexion combinés sont disposées dans une même carte multicouche. La structure de trous d'interconnexion combinés comprend deux parties de travail. La première partie de travail comprend un segment de trou d'interconnexion de signal et une pluralité de segments de trous d'interconnexion de masse entourant le trou d'interconnexion de signal. La seconde partie de travail comprend un segment du même trou d'interconnexion de signal, une pluralité de segments des mêmes trous d'interconnexion de masse, une plaque conductrice lisse et une plaque conductrice ondulée. La plaque conductrice lisse et la plaque conductrice ondulée sont connectées au trou d'interconnexion de signal. La seconde partie de travail comprend un segment du même trou d'interconnexion de signal, une pluralité de segments des mêmes trous d'interconnexion de masse et une plaque conductrice ondulée. La plaque conductrice ondulée est connectée au trou d'interconnexion de signal.
