Yayın A numerical real frequency broadband matching technique based on parametric representation of scattering parameters(IEEE, 1998-11-24) Aksen, Ahmet; Çimen, Ebru Gürsu; Yarman, Bekir Sıddık BinboğaIn this study, a computer, aided broadband matching technique based on the parametric representation of scattering parameters is proposed. The new technique combines the advantageous of the so called parametric approach utilizing the impedance formalizm and the real frequency scattering technique. With the reformulation of these real frequency techniques, some laborous numerical computational steps are omitted. The descriptive network functions are obtained in an explicit form without any need to the polynomial factorizations and the solution of equation sets. The application of the technique and the comparision of the results with those of the other real frequency approaches is discussed on examples.Yayın A computer aided design technique for hybrid and monolithic microwave amplifiers employing distributed equalizers with lumped discontinuities(IEEE, 2001) Aksen, Ahmet; Yarman, Bekir Sıddık BinboğaThis paper will addres the use of mixed lumped and distributed elements in the matching equalizers of microwave amplifers for hybrid and monolithic MIC realizations. In this work we show how the computer aided real frequency technique can be extended to design broadband amplifiers employing distributed equalizers with lumped discontinuities. The scattering based two-variable description of lossless equalizers with mixed lumped-distributed elements will be discussed and the potential benefits of the approach will be indicated by examples.Yayın A parametric approach to describe distributed two-ports with lumped discontinuities for the design of broadband MMIC's(IEEE, 2003) Aksen, Ahmet; Yarman, Bekir Sıddık BinboğaThis paper addreses the use of mixed lumped and distributed elements in the matching equalizers of broadband microwave communication subsytems in MMIC realizations. Construction of two-variable scattering functions for lossless equalizers with mixed lumped-distributed elements is discussed. For the computer aided design and the simulation of lossless distributed two-ports with lumped discontinuity models, a parametric real frequency matching technique is presented. It is expected that the proposed tool will find practical applications for accurate representation of MMIC layouts. A matching network design example is included to systematically exhibit the implementation of the proposed approach.
