Abstract (en)
A superconducting band pass filter (3) has strip conductors (1) formed on the surface of a substrate (5) and contacts are provided to two of the edges (9). The substrate is retained in holders (10) under an applied load. The superconducting device acts as a filter for high frequency signals applied to the contacts. Adjustment of the filter is effected by a pair of mechanical units (16,17) that have pressure elements with contact pads (7,18) that press against the surfaces of the substrate. The displacement applied by the adjusters varies the curvature and the overall length of the filter changes to tune the device. An alternative version uses a magnetic field adjustment effect.
Abstract (de)
Es wird ein Supraleiterbandfilter vorgeschlagen, das auf einem Substrat aufgebrachte Streifenleiter aus einem supraleitfähigen Material aufweist. Es ist eine Abstimmvorrichtung vorgesehen, mittels der die magnetische Eindringtiefe und/oder die effektiven Abmessungen der Streifenleiter und dadurch die Mittenfrequenz und/oder die Bandbreite des Supraleiterbandfilters variierbar ist. <IMAGE>
