Abstract

In this paper, by using two-variable network functions, the explicit characterizations

of lossless ladder networks with lumped and distributed elements are aimed. The explicit

two-variable descriptions of some special classes of lossless ladders networks of low-pass,

high-pass, band-pass and band-reject types are presented. The explicit formulas define the

mixed elements networks under consideration are obtained up to a certain complexity. At

the end of this study, the application of the proposed method in the design of two-stage

microwave FET amplifier is illustrated with an example.

 

ÖZ

Bu çalýþmada, kayýpsýz, iki-kapýlý devrelerin iki-deðiþkenli saçýlma fonksiyonlarý

yardýmýyla oluþturulmasý problemi ele alýnmýþtýr. Bu amaçla, sýnýrlý bazý karma, toplu ve

daðýlmýþ elemanlý iki-kapýlý devre topolojileri incelenerek, ele alýnan devreyi tanýmlayan

saçýlma parametrelerine iliþkin açýk formüller türetilmiþtir. Bu makalede, elde edilen açýk

formüller, 11.7-12.2 GHz band aralýðýnda, MGF2124 mikrodalga tranzistorlerini içeren çift

katlý mikrodalga kuvvetlendirici tasarýmýna uygulanmýþtýr.

Keywords: Two-variable functions, scattering parameters, ladder networks, explicit formulas.
