Subminiature Multi-stage Band-Pass Filter Based on LTCC Technology Research

Bowen Li and Yongsheng Dai
Abstract—A subminiature multi-stage band-pass filter method, which is based on LTCC technology, was studied. The band-pass filter is composed of four good-performance resonator, among which transmission zeros achieved good stopband attenuation through cross coupling. Circuit simulation and the 3D electromagnetic field simulation were used to optimize the simulation. Agreements were found between the experiment results and simulation results. The centre frequency of the four-order band-pass filter is 5.25 GHz and the bandwidth is 500MHz. Insertion loss is over 2.85 dB within the scope of pass-band, in the frequency ranges of 0-4.8 GHz and above 6.3GHz, the out-of-band attenuation is higher than 40 dB. Additionally, the size is only 2.5 mm × 3.2 mm × 1.5mm. The filter range belongs to C spectrum with short wavelength. Hence, the stripline distributed structure was adopted to achieve the miniaturization of the filter.

Index Terms—Band-pass filter, LTCC, strip line, transmission zeros.
