摘要： A filter assembly in a multi-layer printed wiring board. One or more conductors is formed on an internal layer of a printed wiring board. Surrounding dielectric layers and ground layers form, together with the conductors of the internal layer, microstrip or stripline transmission lines and distributed element filters. The filter assembly may include a plurality of internal conductive layers, each sandwiched between dielectric layers and ground layers, and each internal layer may include a plurality of distributed element filters. Connections from each filter to the surface of the filter assembly are formed by vias, and connections from the surface of the filter assembly to a host board are formed by solder joints.

摘要： There is disclosed a planar filter which can variably control a pass frequency band with a high precision and which is superior in skirt property and little in ripple. A planar filter member (1) and tuning member (2) are disposed opposite to each other via a predetermined gap. The filter member (1) is structured in such a manner that an input/output portion (5) formed of a superconductor and a plurality of resonance elements (6) are formed on a substrate (4). The tuning member (2) is structured in such a manner that on the surface of a magnetic plate (7) with a permeability changing by an applied magnetic field, a plurality of dielectric thin films (8), and a plurality of electrodes (9) for applying electric fields to the dielectric thin films (8) are arranged. Each of the dielectric thin films (8) is disposed in a position opposite to a gap between the resonance elements (6) of the filter member (1), or a gap between the filter member (1) and the input/output portion (5). By applying a voltage between the electrodes (9), an effective permittivity ε of the gap between the resonance elements (6), or the gap between the resonance element (6) and the input/output portion (5) is variably controlled, and the skirt property and ripple are adjusted. Moreover, a resonance frequency of the resonance elements (6), a coupling between the resonance elements (6), and a coupling between the resonance element (6) and the input/output portion (5) may be individually and independently controlled.

摘要： A stacked type dielectric filter (10A) comprises two sets of resonators (14A, 14B) arranged in a dielectric substrate (12) constructed by laminating a plurality of dielectric layers, in which each of the resonators (14A, 14B) includes two resonance electrodes (16A, 16B) superimposed in a stacking direction; wherein one resonance electrode (16A) of the two resonance electrodes (16A, 16B) for constructing each of the resonators (14A, 14B) is formed to have a wide width as compared with the other resonance electrode (16B). Accordingly, even when any stacking deviation occurs in the plurality of resonance electrodes during the production, it is possible to decrease the variation of characteristics. Thus, it is possible to maximally exhibit the effect (high Q value, small size, and high performance) to be obtained by constructing the resonator by superimposing the plurality of resonance electrodes in the stacking direction.
摘要翻译：叠层型介质滤波器（10A）包括布置在电介质基板（12）中的两组谐振器（14A，14B），所述电介质基板（12）通过层叠多个电介质层而构成，其中每个谐振器（14A，14B）包括两个谐振电极（16A，16B）叠置在层叠方向上; 其中，用于构成每个谐振器（14A，14B）的两个谐振电极（16A，16B）的一个谐振电极（16A）形成为与另一谐振电极（16B）相比宽的宽度。因此，即使在生产中在多个谐振电极中发生任何堆叠偏移的情况下，也可以减小特性的变化。因此，可以通过在堆叠方向上叠加多个谐振电极来构造谐振器来最大限度地发挥效果（高Q值，小尺寸和高性能）。

摘要： A method is disclosed which allows the electrical characteristics of a microstrip line filter or the like to be reliably measured using a two-dimensional measuring jig, even if components thereof to be measured are small in size and are not discrete components. A first ground electrode is formed substantially over the entire bottom surface of a dielectric substrate (1), and resonator electrodes (11,12,13) are disposed on the top surface of the dielectric substrate (1). Input/output electrodes (21,23) are each connected to a first-stage resonator electrode (11) and a last-stage resonator electrode (13). Second ground electrodes (51) conductively connected to the first ground electrode are disposed beside each of the input/output electrodes (21,23). By this structure, each of the input/output portions is provided with a grounded coplanar guide configuration.
