Abstract

The Simplified Real‐Frequency Method, initiated by Carlin and Yarman in 1982, has rapidly become the most powerful one among the available numerical methods for solving singleor double‐matching problems. So far it has been applied successfully to the synthesis of multistage microwave amplifiers, but the equalizers contained inductors and capacitors only. This article describes the extension of that technique to the direct synthesis of low‐pass and high‐pass distributed matching networks. The main interest of such an extension is to avoid using equivalences between lumped and distributed elements which are not valid in a wide frequency range. In addition, technological constraints are taken into account earlier in the synthesis. Examples are given of bipolar or field‐effect transistor amplifiers which show that LIMDSYN, our in‐house software, is an efficient tool for linear microwave circuit design with distributed elements.
