Abstract

A bandpass Wilkinson power divider with a wide stopband is proposed in this letter. A three-terminal and two-pole bandpass filter and two lowpass filters are employed to substitute two quarter-wavelength transformer in the conventional Wilkinson power divider. The proposed divider achieves not only bandpass response but also a very wide stopband. The rejection is greater than 20 dB up to 22.2 f0. Experiments are carried out to validate design concept of the proposed power divider.
