摘要： A laminated dielectric filter is formed by coupling a plurality of resonators to one another by electromagnetic-field coupling. In the laminated dielectric filter, a bypass circuit formed of a series circuit including bypass capacitors and transmission lines is provided in parallel to a magnetic-field bypass coupling between non-adjacent resonators. Thus, capacitance of the bypass capacitors can be regulated without being affected by the magnetic-field bypass coupling between the non-adjacent resonators. As a result, attenuation poles outside a passband can be controlled freely.

摘要： To provide a laminated band-pass filter comprising at least two band-pass filters without reducing the Q factor of strip line conductors constituting the band-pass filters. A laminated band-pass filter comprises an integrated device formed by laminating and integrating a plurality of dielectric layers together, a plurality of internal grounding conductors formed inside the integrated device, and two band-pass filters sandwiched between two of the plurality of grounding conductors and formed inside the integrated device. One of the band-pass filters has strip line conductors, and the other has strip line conductors. The two band-pass filters are formed in different areas with a boundary between these areas corresponding to a predetermined cross section substantially perpendicular to the grounding conductors.

摘要： A ceramic capacitor includes: a first conductive pattern; a second conductive pattern and a dielectric layer, the first conductive pattern and the second conductive pattern being made of a conductor and provided so as to oppose each other and sandwich the dielectric layer therebetween. The first conductive pattern and the second conductive pattern are different in area from each other, where the second conductive pattern is smaller than the first conductive pattern, and a portion where the first conductive pattern and the second conductive pattern overlap each other forms a capacitance portion. A first extended portion and a second extended portion made of the conductor are formed at both edges of the second conductive pattern so as to extend in mutually opposite directions. With this configuration, the ceramic capacitor with a reduced variation in capacitance value caused by displacement in lamination of green sheets can be provided.
