Abstract

This paper focuses on the application of signal-interference techniques to develop planar multi-band Wilkinson-type power dividers. By inserting transversal signal-interference multi-band filtering cells into the branches of the classic Wilkinson-type power-divider scheme, multi-band power-splitting/combining actions with added filtering operation can be attained. Design formulas for this dual-behavior filtering/power-dividing device for a particular class of embedded multi-band filtering cell are provided. Moreover, a 1.6/3/4.4-GHz triple-band microstrip prototype is built and tested for practical validation.
