Abstract
This paper describes a new pseudo-elliptic structure that has the same number of transmission zeros as comparable Cauer filters. The filter differs from previous structures in that it has two three-section stepped stubs which contribute an additional transmission zero, ensuring even better performance and substantially increased range of realizable stopband attenuation levels.
