Abstract	The paper proposes two kinds of filter structures based on LTCC technology, which includes single layer stepped-impedance microstrip line structure and multilayer structure. According to the design of requirements, two kinds of filter with different structure are designed finally. And the difference between these two kinds of structures is proposed from physical dimensions and performance respectively. Filter in this paper is needed that the cut-off frequency is 1.7 GHz, the attenuation is larger than 30dB at 3GHz and less than 2dB in the pass band. The simulation results show that the two kinds of structures of LTCC filter can meet the desired demand. The single layer stepped-impedance microstrip line LPF has no advantage on physical size and the attenuation rate is lower than the multilayer LPF after 1.7 GHz. So the multilayer structure is dominant in the design of LPF.
