Design Method for Non-Tunable LC-Filters

Analog filter is an important and essential part of electronic devices. LC-Filters are often utilized at frequencies up to about 1 GHz. The influence of parasitic parameters at high frequencies is considerable and significantly distort the frequency response of such filters. Its compensation by the component adjustment brings the serial production sophistication, increases financial and time costs, decreases reliability and resistance to external impacts. This article presents the design method of LC-filters in the VHF range that does not require component adjustment of each filter. The experimental frequency responses of three filters designed by this method are presented.
