DESIGN TABLE FORMATION OF STEPPED IMPEDANCE PROTOTYPE FILTERS

Abstract

In literature, there exist some tables containing normalized element values, to design low-pass lumped-element prototype filters with several different responses like maximally flat or equal-ripple. In this work, an algorithm is presented, to form such tables for stepped impedance prototype filters. By using the proposed algorithm, a table for 0.5 dB equal-ripple stepped impedance prototype filter is formed. Then a design example is given, to show the utilization of the formed table

Keywords

• Filters, Stepped impedance, Maximally flat, Equal ripple, Distributed elements
