Abstract
The aim of the paper is to produce complete design data (i.e. the values of components in terms of generalized frequency and load conditions) of symmetrical equally terminated filters consisting of reactances only. The data are produced in graphical form and are carefully plotted to slide-rule accuracy; they are sufficiently dense to cover fully the usual requirements, without the use of interpolation.The filters are designed on the basis of Darlington's insertion-loss theory with Cheby̅shev behaviour both in the pass band and in the attenuation band. This allows for the unique correlation of the usual design specifications, which is displayed in a graphical form.The underlying theory of the quadripoles and of the realization procedure is explained fully and independently of the practical part of the paper.Finally, proper alignment procedure is described.
