摘要
设计了一种小型化的LTCC低通滤波器,采用LC集总元件完成原理图的设计与仿真,使用HFSS完成滤波器结构的三维电磁场仿真,最终在LTCC工艺线上完成加工制作。LTCC滤波器使用介电常数7.8、损耗角为0.006的生瓷片,内部导体电路印刷使用配套的银浆料,最终尺寸为3.2 mm×1.6 mm,厚度为1.4 mm,达到小型化的目的,可应用于移动通信等领域。
Firstly a new type miniaturized LTCC filter is designed in this paper, the design and simulation of the filter schematic was completed based on LC lumped elements. Besides a filter model was simulated in Ansoft-HFSS. Finally a product sample was manufactured. The LTCC material is a dielectric constant er of 7.8, a loss tangent of 0.006. the inner conductor sliver paste which must be compatible with the LTCC green tape. The LPF is small size 3.2 mm×1.6 mm, thickness is 1.4 mm. It can be widely employed in compact microwave communication systems.
