    • PROBLEM TO BE SOLVED: To provide a filter device having a low insertion loss. SOLUTION: The filter device includes: a hollow housing 13 to which an input connector 12 is connected; and a resonant element 14 provided in the housing 13. A metal frame body 13b having an opening 13a below, and a resin cap 15 fixed to the opening 13a and having a conductor part 15a formed on at least its upper surface are provided to the housing 13. The conductor part 15a closes the whole opening 13a, the end part of the opening 13a side of the housing 13 and the conductor part 15a are connected by a solder 16. A leg part 17c extending from the front edge of a side plate 17b, and a hole 15b provided to the cap 15 and to which the leg part 17c is inserted, are provided. The root of the leg part 17c has a protrusion 17d for forming a fillet 16b by the solder 16 with the conductor parts 15a. The fillet 16b is formed also at the leg part 17c to provide a filter device 11 having the low insertion loss. COPYRIGHT: (C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To control the frequency of the low attenuation's peak generated at a frequency higher than a passband due to a coupling path without impairing the function of the coupling path for forming an attenuation pole at a frequency lower than the passband. SOLUTION: The bandpass filter 1 includes three resonators 4, 5 and 6 of which adjacent two are electromagnetically coupled to each other, and two coupling paths 7 and 8 connected in parallel for forming capacitive coupling between nonadjacent two resonators 4 and 6. The coupling path 7 includes a capacitor 21, an inductor 23 and a capacitor 22 connected in series. The coupling path 8 includes a capacitor 24, an inductor 26 and a capacitor 25 connected in series. The coupling paths 7 and 8 function to form an attenuation pole at a frequency lower than the passband in the pass/attenuation characteristics of the bandpass filter. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:为了控制由于耦合路径而在高于通带的频率处产生的低衰减峰值的频率,而不损害用于形成低于通带频率的衰减极点的耦合路径的功能 。 带通滤波器1包括三个谐振器4,5和6,其中相邻的两个谐振器4,5和6彼此电磁耦合,以及两个并联连接的耦合路径7和8,以在非相邻的两个谐振器4和6之间形成电容耦合。 耦合路径7包括串联连接的电容器21,电感器23和电容器22。 耦合路径8包括串联连接的电容器24,电感器26和电容器25。 耦合路径7和8用于在带通滤波器的通过/衰减特性中形成的频率低于通带的衰减极点。 版权所有(C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a filter device having less passage loss. SOLUTION: This filter device includes: a frame body 13b formed of a surface treated steel sheet having a metal surface; a lid 15 attached to an opening 13a of the frame body 13b; a partition 13c for partitioning the inside of the frame body 13b; a plurality of hollow portions 12 partitioned by the partition 13c; and coupling windows 12a for coupling the adjacent hollow portions 12 among the hollow portions 12. A front end of the opening 13a is connected to the lid 15 via a solder 16, and the partition 13c is made of a double-sided copper-clad substrate having copper foils 24 formed on both surfaces. The copper foils 24 are electrically connected to a conductor portion 15a of the lid 15 at the lower side of the partition 13c, and the copper foils 24 are connected to the frame body 13b via a solder 16 at the upper side of the partition 13c. Thus, since the partition 13c is non-magnetic, the filter device having less passing loss can be achieved. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:提供具有较少通道损失的过滤装置。 解决方案:该过滤装置包括:由具有金属表面的表面处理钢板形成的框体13b; 附接到框体13b的开口13a的盖15; 用于分隔框体13b的内部的分隔件13c; 由分隔件13c分隔的多个中空部分12; 以及联接窗口12a,用于将相邻的中空部分12联结在中空部分12之间。开口13a的前端通过焊料16连接到盖子15,并且隔板13c由双面铜包覆基板 在两个表面上形成铜箔24。 铜箔24在分隔件13c的下侧电连接到盖子15的导体部分15a,铜箔24通过分隔件13c上侧的焊料16与框体13b相连。 因此,由于分隔件13c是非磁性的,所以可以实现具有较小通过损失的过滤装置。 版权所有(C)2011,JPO&INPIT
