【摘要】 设计制作了一种基于微波多层结构的折叠型交指滤波器。该滤波器将传统交指型结构进行小型化设计,尝试建立多层纵向折叠方案的三维模型,设计了一种6-8GHz带宽的交指型小型化滤波器。在HFSS软件上对该滤波器进行仿真验证,然后制作实物。该滤波器相较于传统交指结构电路面积减小超过50%,带内插入损耗小于2d B,回波损耗优于-10d B,尺寸为7.5*4mm,同时保持较高频带选择性与不错的带内特性。更多还原

【Abstract】 A foldable cross-index filter based on microwave multilayer structure is designed and fabricated. This filter is used to miniaturize the traditional interdigital structure, and try to build a three-dimensional model of multi-layer longitudinal folding scheme, designs a cross-finger miniaturized filter for 6-8 broadband applications. The filter is simulated and verified on the HFSS software, and then the physical object is made. Compared with traditional cross-finger structure, the area of the filter is reduced by more than 50%, the passband insertion loss is less than 2 dB, the return loss is better than-10 dB, and the size is 7.5*4 mm, while maintaining high frequency band selectivity with good in-band characteristics.更多还原
