【摘要】 介绍了一种悬置带状线正反面耦合的高通滤波器,采用LC滤波器模型,再用悬置带状线结构模拟实现其串并联电容电感,借助EDA软件对其仿真优化实现,在一块介质厚度为0.254mm、铜层厚度为0.018mm的Rogers5880板材上制作了该结构的高通滤波器。测试数据显示该滤波器体积小,重量轻,边带抑制好。更多还原

【Abstract】 This paper introduces a high-pass filter using suspended striplines with front-back coupling,which uses the LC filter model,then adopts the suspended striplines structure to realize the series-parallel connection of capacity and inductance,uses EDA software to realize the simulation and optimization,makes the high-pass filter of this structure on a 0.254 mm Rogers 5880 plate with 0.018 mm copper layer.Testing data show that the filter possesses the excellence of small size,light weight and good sideband suppression performance.更多还原
