摘要： A band-pass filter includes a metal film provided on a dielectric body. The shape and size of the metal film and the coupling points of input-output coupling circuits are selected such that first and second resonance modes are generated. The metal film has protruding portions or concavities provided thereon such that resonance electric field strength in the first or second resonance mode is controlled to couple the first and second resonance modes to each other.

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 for forming a resonator is arranged on a first main surface of a dielectric body or at a certain height in the dielectric body. At least one ground electrode is arranged such that the ground electrode is opposed to the metal film via the dielectric body. The metal film is connected to input/output coupling circuits. In the region where the metal film is opposed to the ground electrode, two portions 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.

摘要： A plurality of capacitor elements defined by first and second capacitor electrodes are formed in the interior of a laminated ceramic block, while a plurality of first terminal electrodes to be electrically connected to the first capacitor electrodes and a ground terminal electrode to be connected to the second capacitor electrodes in common are formed on one side surface of the block. A plurality of resistor films are formed on a major surface of the block, to be connected to the first terminal electrodes. A plurality of second terminal electrodes are formed on another side surface of the block, to be electrically connected to the resistor films. Another ground terminal electrode is formed on this side surface, to be connected to the second capacitor electrodes in common. Thus, an RC array being applicable to a high frequency filter array is integrated and miniaturized to cope with high density packaging, as well as to enable surface mounting.
