Abstract

Beschrieben wird eine HF-Filteranordnung (1) mit mindestens zwei Topfkreis-Resonatoren (2, 3), die über eine gemeinsame, elektrisch leitende Topfwand (4) oder über jeweils elektrisch miteinander verbundene Topfwände gekoppelt sind, wobei in der gemeinsamen Topfwand (4) oder in den elektrisch miteinander verbundenen Topfwänden ein Koppelfenster (5) eingebracht ist, das vollständig von elektrisch leitendem Material (6) umschlossen und in dem ein Koppelmittel (7) mit variabel einstellbarer Kapazität eingebracht ist.Described is an RF filter arrangement (1) with at least two cup-circle resonators (2, 3), which are coupled via a common, electrically conductive pot wall (4) or via each electrically interconnected pot walls, wherein in the common pot wall (4) or in the electrically interconnected pot walls, a coupling window (5) is introduced, which is completely enclosed by electrically conductive material (6) and in which a coupling means (7) is introduced with variably adjustable capacity.

Die HF-Filteranordnung zeichnet sich dadurch aus, dass das Koppelmittel (7) ein elektrisch leitendes Stabelement (8) mit einer Stabachse (9) sowie zwei Stabelementenden (10, 11) aufweist, das beidseitig über die Stabelementenden (10, 11) mit dem das Koppelfenster (7) umschließenden elektrisch leitenden Material (6) elektrisch leitend verbunden ist, und dass elektrisch isoliert zum Stabelement (8) wenigstens zwei elektrisch miteinander verbundene, aus elektrisch leitendem Material gefertigte Fingerelemente (12, 13) am Stabelement (8) derart befestigt sind, dass die Fingerelemente (12, 13) um eine mit der Stabachse (9) zusammenfallende Drehachse (19) drehbar gelagert sind.

Figure imgaf001
The RF filter arrangement is characterized in that the coupling means (7) has an electrically conductive bar element (8) with a bar axis (9) and two bar element ends (10, 11), which on both sides via the bar element ends (10, 11) with the the coupling window (7) enclosing electrically conductive material (6) is electrically connected, and that electrically insulated to the rod member (8) at least two electrically interconnected, made of electrically conductive material finger elements (12, 13) attached to the rod member (8) in that the finger elements (12, 13) are rotatably mounted about an axis of rotation (19) coinciding with the rod axis (9).
