Abstract

Die Frequenzstabilität eines Bandpaßfilters, das aus einer Anzahl von n (n ≥ 2) Hohlleiterresonatoren (A, B) besteht, von denen die jeweils benachbarten mechanisch miteinander verbunden und elektrisch über mindestens eine Öffnung in einer Trennwand gekoppelt und der erste sowie der n-te Resonator durch je eine Endblech verschlossen sind, läßt sich dadurch verbessern, daß die benachbarten Resonatoren (A, B) jeweils eine eigene Trennwand (1, 2) mit der mindestens einen Koppelöffnung haben und voneinander um einen Zwischenraum (Z) zwischen den Trennwänden (1, 2) beabstandet sind, der durch einen die Koppelöffnungen verbindenden Rohrstutzen (3) überbrückt ist und daß der Zwischenraum (Z) zum Abtransport von Wärme ausgebildet ist.

Figure 00000001
The frequency stability of a bandpass filter, which consists of a number of n (n ≥ 2) waveguide resonators (A, B), of which the respectively adjacent ones are mechanically connected to one another and electrically coupled via at least one opening in a partition and the first and the nth Resonator are closed by an end plate each, can be improved in that the adjacent resonators (A, B) each have their own partition (1, 2) with the at least one coupling opening and from each other by an intermediate space (Z) between the partition walls (1 , 2) are spaced, which is bridged by a pipe socket (3) connecting the coupling openings and that the intermediate space (Z) is designed to remove heat.
