摘　　要：多频段射频通信采用集成的多频段带通滤波器,该滤波器以环形谐振器为基础,如同心圆介质环形谐振器。通过使用同心环结构构造多频带通滤波器,大大降低了在多频带运行的多滤波器对印刷电路板(PCB)的实际需求。基于同心圆谐振器的多频带通滤波器的各种配置为移动设备的多频带移动设备的布局设计和制造提供了灵活性。这些同心圆谐振器的配置可以包括但不限于槽耦合配置、直接耦合配置和嵌入式直接耦合配置。在封装技术中具有重要作用。An integrated multi⁃band band⁃pass filter based on ring resonators like concentric dielectric ring resonators is adopted in the multi⁃band radio frequency communication.The application of multi⁃band band⁃pass filter constructed with concentric ring structure can significantly reduce the actual requirement of the multiple filters operating in multi⁃band for the printed circuit board(PCB).Various configurations of the multi⁃band band⁃pass filter based on the concentric ring resonator provide flexibility for the layout design and manufacturing of multi⁃band mobile devices in the mobile equipments.The configurations of these concentric ring resonators include but are not limited to slot⁃coupling configuration,direct⁃coupling configuration and embedded direct⁃coupling configuration.Therefore,it plays an important role in packaging technology.
