Synthesis of a useful class of transmission line networks

摘要

AbstractA general class of networks consisting of cascaded commensurate transmission lines and shunt imaginary conductances is considered. This kind of network performs an excellent approximation to transmission line networks with shunt stubs or lumped elements. The realizability conditions for the driving‐point admittance and transfer function have been given in a previous paper. The imaginary conductances were generated by introducing an extra phase angle into the scattering function. In the present paper two alternative methods are given1by identifying in different ways the roots of the numerator polynomial in the input scattering function.2by using non‐symmetric gain functions.The influence of different factorizations and non‐symmetric gain functions upon the element values variation is exa
