Analysis of the Parasitic Parameters Influence on the Analog Filters Frequency Response

Modern tools for the synthesis of analog filters cannot automatically solve the problem of designing filters in the VHF range on concentrated non-tunable elements of minimal dimensions. The reason for this is unaccounted parasitic parameters that do not yet have a significant effect at lower frequencies, while at higher frequencies filters with distributed parameters become preferable. The article provides an assessment of the influence of various parasitic parameters on the frequency response of a bandpass filter.
