Abstract

A kind of Wilkinson power divider with bandpass filtering response is presented in this letter. In the proposed power divider, two bandpass filters are used to substitute two quarter-wavelength transformer in a conventional Wilkinson power divider. This kind of Wilkinson power divider has two transmission zeros out of the passband. One transmission zero is created by the dual mode resonator intrinsic characteristics. The other is introduced by the source-load coupling. Different transmission zeros could be achieved by changing the dimension of the dual mode resonator or the source-loading coupling. Two experimental circuits are fabricated by the traditional printed circuit board technology. The measured and simulated results are in good agreement.
