Publisher and Date:(World Scientific Publ Co Pte Ltd, 2017)In this paper a new approach based on the real frequency technique (RFT) has been proposed to solve broadband matching problems using cascaded unequal length transmission lines. At the end of the design process optimum characteristic impedance and delay values of transmission lines are obtained. Two examples are given to illustrate the utilization of the proposed approach.
Publisher and Date:(Elsevier GMBH Urban & Fischer Verlag, 2009)In general commercially available software tools are preferred to design broadband matching networks for wireless communication systems. But they need a properly selected matching network topology with good initial element values. Therefore in this paper a new real frequency technique is presented to generate broadband single matching networks with suitable initial element values. In the proposed method load impedance is written in terms of ABCD-parameters of the desired matching network and the ...
Design of impedance matching network for B&K 8104 hydrophone via Direct Computational Technique for underwater communication Authors:
Publisher and Date:(2010)Underwater acoustic communication is a rapidly growing field of applied research and is a technique of sending and receiving message below water. There are several ways of doing such communication but the most common one is realized by using transducers. In underwater acoustic communication one of the most important problems is driving the transducers with matched network. In this study design of impedance matching network for B&K 8104 hydrophone that can be used for underwater communication was ...
High-pass/low-pass section design for 0 degrees-360 degrees lumped-element phase shifters via the real frequency technique Authors:
Publisher and Date:(TUBITAK Scientific & Technical Research Council Turkey, 2017)In this paper an algorithm based on the real frequency technique (RFT) is proposed to design high-pass and low-pass sections of a 0 degrees-360 degrees wide range lumped-element phase shifter. The switching process however is not considered in this work. In the algorithm it is enough to define the section type (high-pass or low-pass) and the number of elements in the sections there is no need to select the exact circuit topologies for the high-pass and low-pass sections. This is a natural consequence ...
