摘要： A dual mode band pass filter is constructed to be very compact and such that the coupling strength and bandwidth can be easily and widely adjusted while maintaining sufficient freedom of design. A metal film (3) for forming a resonator is arranged on a first main surface of a dielectric body (2) or at a certain height in the dielectric body (2). At least one ground electrode (4) is arranged such that the ground electrode is opposed to the metal film (3) via the dielectric body (2). The metal film (3) is connected to input/output coupling circuits (5,6). In the region where the metal film (3) is opposed to the ground electrode (4), two portions (2a,2b) are partially provided. Each of these two portions has a relative permittivity that is different from the relative permittivity of the remaining portion, in order to couple two resonance modes. In another embodiment, the ground electrode is provided with openings (4a,4b), in order to couple two resonance modes.

摘要： The invention concerns a method of tuning planar superconductive filters by means of a vertically adjustable housing cover which enables the mid-frequency of the band-pass filter to be set. In this way, the filters can be tuned considerably more easily. The invention also concerns the construction of a filter bank for multiplex applications.

摘要： Resonator electrodes (11, 12, 13) are provided on the upper face of a dielectric substrate (1). The ratios (W1/L1) and (W3/L3) of the electrode lengths L1 and L3 to the electrode widths Wl and W3 of the resonator electrodes (11, 13) of the first and last stages are set at 1 or higher. Lead-out electrodes (21, 23) are connected to the resonator electrodes (11, 13) of the first and last stages on the opposite sides of the center axis which is a straight-line axis passing through the center positions of the electrode lengths of the resonator electrodes (11, 13) of the first and last stages. Thereby, an attenuation pole is generated on the lower band side of the pass-band.

摘要： Inductor patterns (21a, 21b; 22a, 22b) are electrically connected to each other through long via-holes (28) formed in sheets, so that tubular structures (21, 22) each having an insulator filled therein and having a rectangular cross section are formed, respectively. The tubular structures (21, 22) are laminated through sheets to form an inductor (L1) having a double structure. A capacitor pattern (23) is opposed to the open ends of the inductor patterns, respectively, to form a capacitor (C1). That is, the capacitor pattern (23) is arranged between the tubular structures (21, 22). The capacitor (Cl) and the inductor (L1) having the double structure form an LC parallel resonance circuit.
