Researching of the Tolerances Limiting in the Microstrip Filters Designs, Considering a View of Approximation Amplitude-Frequency Characteristics

Probing tolerance limitings on the geometrical sizes constructions of the microstrip filters is carried out. Also, view of approximation amplitude-frequency characteristics, providing the necessary characteristics of the filter take into account. The synthesis of filters is fulfilled on the basis filters- prototypes of the lower frequencies. Calculation of tolerances is made with usage of interval models. The registration agency of manufacture technology of the filters topology is carried out by introduction of weight coefficient.
