Özet

In this study, the realization problem of matching network consisting of Brune sections is investigated. In the synthesis of a general impedance function with finite transmission zeros, each transmission zero extraction results in a Brune section involving a negative reactive element. Although coupled inductances can be used to remove negative elements, a direct mutual coupling free ladder design is aimed by properly incorporating the mid-shunt ladder realizability conditions of Fujisawa. For this purpose, impedance based Real Frequency Technique (RFT) is used to construct realizable impedance function and Fujisawa synthesis procedure is applied for mid-shunt ladder realization. An illustrative matching network design example is presented.
