Title (EN) A COMPOUND WITH TRIMMABLE ELECTRIC IMPEDANCE I.E.A STUB
(FR) COMPOSANT A IMPEDANCE ELECTRIQUE REGLABLE, AUTREMENT DIT BRAS DE REACTANCE
Abstract: front page image
(EN)A uniform electric component realizing a resistive-capacitive impedance, or a stub, comprising such a parallel connection of shorted and open structures of various lengths and widths of distributed RC-structures, where different structures are manifested as a steplike or smoothened shape of the line opposite the driving point of the component. The structures are also manifested as a mutual electric connection or disconnection between the resistor layer (13) and the ground plane (221) at various points of the said line. The measures of the stub are defined in a successive iteration process between the employed frequencies (f1, f2...) and the required admittances (Y1, Y2...). The stub is trimmed by shortening it or by removing or disconnecting one or more layers so that the endline of the remaining structure becomes perpendicular to the conduction band (211). The stub can also be manufactured as a reversibly trimmable structure. The stub can be used as part of a bandrejection filter.
(FR)Composant electrique uniforme constituant une impedance resistive-capacitive, ou un bras de reactance, comprenant une connexion en parallele de structure fermee et ouverte de differentes longueurs et profondeurs de structures RC distribuees, ou les differentes structures presentent une forme en gradin ou aplanie de la ligne opposee au point de commande du composant. Les structures apparaissent aussi en tant que connexion ou separation electrique mutuelle entre la couche (13) de resistance et le plan de base (221) a des points differents de ladite ligne. Les mesures du bras de reactance sont definis lors d"un procede successif d"iteration entre les frequences utilisees (f1, f2...) et les admittences requises (Y1, Y2...). Le bras de reactance est ajuste en le raccourcissant ou en enlevant ou separant une ou plusieurs couches de maniere telle que la ligne d"extremite de la structure restante devienne perpendiculaire a la bande de conduction (211). Le bras de reactance peut aussi etre fabrique sous forme de structure reglable de maniere reversible. Le bras de reactance peut etre utilise en tant que partie d"un filtre suppresseur de bande.
