A novel structure cavity filter, cross-coupled 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 double-layer 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.
