Design of LC bandpass filters based on silicon-based IPD Technology

Compared with the traditional vertical LC filter, integrated passive filters on silicon substrate have the advantages of small size, flexible design, high performance and low power consumption. In this paper, based on the basic principle of microwave filters, a LC bandpass filters with a pass band range of 2.3GHz-2.6GHz is designed by using software such as ADS and HFSS. After the simulation optimization meets the performance index, the LC filter is processed and manufactured based on silicon-based Integrated Passive Devices (IPD) Technology. The vector network analyzer is used to test the filter. The results show that the LC bandpass filter meets the design index and achieves good filtering effect in the passband range.
