摘要： A filter for filtering electrical signals comprises a substrate and a plurality of resonators formed circularly to surround the center of the substrate. Each resonator has an arcuate part at a radially outermost part and a pair of linear parts extending from ends of the arcuate part in a radially inward direction. The arcuate part is located at the same distance from the center of the substrate. The linear parts of each resonator have different lengths from each other thereby to provide a sharp decrease of gain at ends of the frequency passband in a filtering response.

摘要： A filter has a plurality of resonators formed regularly on a substrate and made of a superconducting material. In measuring resonance frequency of the resonators, the filter and a conductive metal plate having an opening are placed in a vacuum chamber so that all the resonators other than one resonator which faces the opening are covered with the metal plate. The metal plate has an input probe and an output probe at the opening of the metal plate. The resonance frequency of each resonator is measured in sequence while rotating the metal plate. Each resonator is adjusted in shape by a laser trimming or providing a dielectric film in correspondence with the measured resonance frequency so that all the resonators have a fixed resonance frequency.
