摘要： An improved design for microwave bandpass cavity filters wherein dielectric resonator elements are mounted in dielectric blocks (there can be more than one resonator element per dielectric block). The dielectric blocks are in turn fitted within the filter housing, and the open ends are covered by shorting plates which are maintained in contact with each resonator surface. The shorting plates may be coated with a superconductive material. The structure results in significant size reduction over prior art filters. In addition, the new design is of higher structural integrity and helps to maintain a consistent output over a wide range of temperatures. By carefully choosing the dielectric materials to insure uniform thermal expansion of the component parts, the filter output is stable over a wide range of temperatures. This allows the filters to be tuned while at cryogenic temperatures, then returned to room temperature for storage or shipping, and finally return to cryogenic temperatures for operating purposes. The filters can be constructed with various configurations and can be operated in single mode, dual-mode, triple-mode, etc.

摘要翻译：用于微波带通腔滤波器的改进的设计，其中介质谐振器元件安装在介质块中（每个介质块可以有多于一个谐振元件）。介质块又装配在过滤器壳体内，开口端由与每个谐振器表面保持接触的短路板覆盖。短路板可以涂覆有超导材料。与现有技术的过滤器相比，该结构导致显着的尺寸减小。此外，新设计具有更高的结构完整性，有助于在宽温度范围内保持一致的输出。通过仔细选择电介质材料以确保组件的均匀热膨胀，滤波器输出在宽的温度范围内是稳定的。这允许过滤器在低温下进行调节，然后返回到室温进行储存或运输，最后返回到低温温度进行操作。滤波器可以用各种配置构成，可以在单模，双模，三模等操作。
