Abstract

The procedure of optimization of microstrip filter tolerances allowing for correlation of member tolerances is proposed. The filters realized on the basis of elements with lumped parameters are considered. The model for calculating tolerances is shaped by mapping transfer functions into the space of interval values. The offered interval models take into account the distributed character of a transmission line of a signal. The results of optimization for the microstrip low-pass filter are given. Members most critical to tolerances are defined.
