Recently, Richards proved the remarkable fact that the synthesis of networks consisting of resistors and lossless transmission-lines with finite electrical length may be treated exactly the same way as in the case of conventional linear passive networks. This paper offers a new synthesis of this kind without mutual induction and its application to the design of uhf filters having Tchebyscheff characteristics in both pass and attenuation bands. The synthesis problem treated here is, in other words, the analog of the so-called Darlington problem in conventional lumped constant networks. Approximation procedures for filter characteristics are based on the well-known potential analogy.
