A broadband microwave amplifier design by means of immittance based data modelling tool
Authors:
Publisher and Date:(IEEE, 2002)In this paper a practical broadband microwave amplifier design algorithm is introduced utilizing the immittance data-modelling tool. In the course of design first the optimum input and output terminations for the active device are produced employing the real frequency technique. Then these terminations are modelled utilizing the new immittance-modelling tool to synthesize the front-end and back-end matching networks. An example is included to exhibit the implementation of the proposed design ...

Broadband Equalizer Design with Commensurate Transmission Lines via Reflectance Modeling
Authors:
Publisher and Date:(IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, 2008)In this paper an alternative approach is presented to design equalizers (or matching networks) with commensurate (or equal length) transmission lines. The new method automatically yields the matching network topology with characteristic impedances of the commensurate lines. In the implementation process of the new technique first the driving point impedance data of the matching network is generated by tracing a pre-selected transducer power gain shape without optimization. Then it is modelled its ...

Design of broadband microwave amplifiers with mixed-elements via reflectance data modeling
Authors:
Publisher and Date:(Elsevier GMBH Urban & Fischer Verlag, 2008)A practical method is introduced to design single-stage broadband microwave amplifiers with mixed lumped and distributed elements via modeling the reflectance data obtained from lumped-element input and output matching network prototypes. The same transducer power gain level is obtained by using less number of lumped-elements in the mixed-element amplifier than that of the lumped-element amplifier prototype. A mixed-element amplifier design is presented to exhibit the utilization of the method. ...

Design of distributed-element RF filters via reflectance data modeling
Authors:
Publisher and Date:(Elsevier GMBH Urban & Fischer Verlag, 2008)A reflectance-based modeling method is presented to obtain the distributed-element counterpart of a lumped-element network which is described by measured or computed reflectance data at a set of frequencies. Numerical generation of the scattering parameters forms the basis of this modeling tool. It is not necessary to select a circuit topology for the distributed-element model which is the natural consequence of the modeling process. Our approach supplements the known interpolation methods by a ...

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 ...

Design of practical matching networks with lumped elements via modeling
Authors:
Publisher and Date:(IEEE, 2007)It is a common practice to utilize commercially available software tools to design matching networks for wireless communication systems. Most of these tools require a properly selected matching network topology with good initial element values. Therefore in this paper a practical method is presented to generate matching networks with initial element values. In the implementation process of the proposed method first the driving point immitance data for the matching network is obtained in a straight ...
