提出了一种新型结构的空腔滤波器——双层结构的交叉耦合多空腔滤波器。定性和定量地分析了交叉耦合的传输零点，总结了仿真建模的一些设计经验，研究了双层结构同步调谐耦合谐振器的磁耦合和电耦合。仿真和实验结果表明，双层结构的交叉耦合多腔滤波器既能满足高选择性要求，又能节省空间，有利于小型化设计。通过实验样品和设计模型处理的六极双层基站滤波器的测量结果，充分验证了双层多腔滤波器的可行性、实用性和优越性能。
A novel structure cavity filter, crosscoupled multi-cavity filter with double-layer structure is proposed. The transmission zero of cross coupling is analyzed qualitatively and quantitatively, while some of the design experience of simulation modeling are summed up and the magnetic coupling and electric coupling of synchronously tuned coupling resonators with double-layer structure are studied. Simulation and experimental results show that the cross-coupled multi-cavity filter with doublelayer structure not only can meet the high selectivity requirements, but also save space, which is conducive to miniaturization design. The feasibility, practicability and superior performance of the double-layer multi-cavity filter are fully verified by the experimental samples and the measurement results of the six-pole double-layer base station filter processed by the design model.
