    • A waveguide-type dielectric filter suitable for wideband filter applications made of a metallized dielectric material is provided. The filter includes two or more mutually coupled resonators disposed in a longitudinal manner. The coupling between adjacent resonators is provided and adjusted by slots or through holes. The dielectric block is covered with metal ground coating with the exception of an uncoated area at the input and output that creates two contact pads on one surface of the dielectric block that are electrically isolated from the metal ground coating. Metallized blind holes are formed on the opposing surface of the dielectric block with respect to the contact pads. These blind holes effectively move the ground plane closer to the contact pad, which, in turn increases the coupling between the input and output resonators and external circuitry, which is essential for building wide bandwidth band pass filters,
    • 提供适用于由金属化介电材料制成的宽带滤波器应用的波导型介电滤波器。 滤波器包括以纵向方式设置的两个或更多个相互耦合的谐振器。 相邻谐振器之间的耦合由槽或通孔提供和调整。 除了输入和输出处的未涂覆区域之外,介质块被金属地面涂层覆盖,从而在介质块的一个表面上产生与金属地面涂层电隔离的两个接触焊盘。 金属化盲孔相对于接触焊盘形成在介质块的相对表面上。 这些盲孔有效地将接地层移近接触焊盘,这反过来又增加了输入和输出谐振器与外部电路之间的耦合,这对于构建宽带宽带通滤波器是必不可少的,

    • A discrete resonator is provided, including a dielectric base having a dielectric constant. A metal contact formed on a major surface of the dielectric base has a predetermined area and is positioned at a predetermined location on the dielectric base to provide a predetermined loaded Q for the resonator. A metal ground coating is formed on the outer surface of the dielectric base with the exception of an isolation region surrounding the metal contact that is free of the metal ground coating. The area of the isolation region is sufficient to prevent significant coupling between the metal contact and the metal ground coating. The dielectric constant of the material used for the base, and the width and length of the dielectric base are each selected such that the resonator resonates at least at one predetermined resonant frequency in the GHz frequency range.
    • 提供了分立的谐振器,包括具有介电常数的电介质基底。 形成在电介质基底的主表面上的金属接触件具有预定的面积并且位于电介质基底上的预定位置处,以为谐振器提供预定的加载的Q。 金属接地涂层形成在电介质基体的外表面上,除了围绕金属接触件的隔离区域,该隔离区域没有金属地面涂层。 隔离区域的面积足以防止金属接触和金属地面涂层之间的显着的耦合。 用于基底的材料的介电常数以及电介质基底的宽度和长度各自被选择为使得谐振器在GHz频率范围内至少谐振至少一个预定的谐振频率。
