Modeling Based Real Frequency Technique

Abstract

Usually commercially available software tools are used to design matching networks for wireless communication systems. But a properly selected matching network topology with good initial element values must be supplied to these tools. Therefore in this paper a modeling-based real frequency technique (M-RFT) is presented to generate matching networks with initial element values. In the proposed method output impedance data of the matching network are obtained in terms of ABCD-parameters of the load model. Then they are modeled which in turn yields the desired matching network with initial element values. It is not needed to select a circuit topology for the matching network which is the natural consequence of the matching processes. Also there is no need to select the desired transducer power gain levelthe proposed technique naturally provides a gain curve fluctuating around a flat level. Eventually the initial design is improved by optimizing the performance of the matched system employing the commercially available computer aided design (CAD) packages. An algorithm and example are given to illustrate the utilization of the proposed technique. (C) 2007 Elsevier GmbH. All rights reserved.
