@@@@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 εr 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.
