Design Tables for an Elliptic-Function Band-Stop Filter (N=5)

Design tables for a wide-band elliptic-function band-stop trammission-line filter are described. The filter consists of five alternating quarter-wave and half-wave stubs separated by quarter-wave lines. The characteristic impedances of the filter elements were computed from published tables of the lumped-element prototype by an exact method. The filter elements are assumed to be lossless.
