Abstract

A compact ultra-wideband (UWB) power divider with favorable selectivity is proposed. A transversal filtering transformer consisting of two different centrally loaded resonators with common feeding lines is introduced at input port to obtain good in-band response and high out-of-band rejection. Simple and rapid design procedure is adopted to find the key parameters. A prototype power divider is designed and fabricated to validate the predicted features. Measured results show that the power divider is featured by sharp roll-off skirts and large stopband attenuation.
