Resonant filter chip

The invention relates to a resonant filter chip, which comprises a plurality of resonant units and input and output feeders, and is characterized in that the input and output feeders feed microwave energy into a filter; more than two coupling channels are formed by the resonance units between the input and the output, at least one channel comprises slot coupling, and at least one channel comprisesedge coupling. Miniaturization of the filter chip is achieved, assembly and integration are convenient, and the filter chip is suitable for a miniaturized and high-integration-level radar system. 本发明一种谐振滤波器芯片，包括若干个谐振单元，和输入输出馈电线组成，所述输入与输出馈电线是把微波能量馈入滤波器；输入与输出之间由谐振单元构成两条以上耦合通道，其中至少一条通道包含缝耦合，至少一条通道包含边耦合。本发明实现滤波器芯片小型化、便于装配和集成，适用于小型化、高集成度的雷达系统。
