摘要
对滤波器交叉耦合技术进行了研究,分析了交叉耦合的矩阵理论,并大致分析了其拓扑结构。从理论上提出了交叉耦合三维拓扑模型,相对于实际应用中的二维拓扑模型,这种结构更为简单,更能充分利用各个耦合腔之间的耦合结构。把交叉耦合结构应用于LC滤波器设计中,计算与仿真结果表明,这种结构可以减少滤波器元器件数目,降低成本,提高性能。
The technology of cross-coupled filter is analyzed in this paper, the theory of cross-coupled matrix and its topology is also analyzed. A three-dimensional cross-coupling topology model is toke out in theory. Compared with the topology of two-dimensional model, this structure is simpler and flexible. And the technology of cross-coupling is used in the design of LC filter, calculation and simulation results show that such a structure can reduce the number of filter components, reduce costs and improve performance.
