Exact Ladder Network Design Using Low-Q Coils

In preceding papers, tables were presented for the design of lossless networks terminated in resistance at one or both ends. Networks with uniform dissipation and a resistance termination only at the load end are considered in this paper. The tables give the element values of normalized low-pass ladders with one of the following characteristics: maximally flat magnitude (Butterworth), equal-ripple magnitude (Tchebycheff), and maximally flat time delay (Bessel polynomial). The low-pass to band-pass frequency transformation can be used on the Butterworth and Tchebycheff networks to yield the element values for the band-pass case.
