Miniaturized Wilkinson Power Divider with DC Isolation

Abstract

This paper presents a miniaturized Wilkinson power divider with DC isolation. By using parallel coupled lines, we can achieve DC isolation while maintaining good RF bandwidth. We compare the proposed design with the previously proposed design. The measurement results of the fabricated Wilkinson power divider exhibit good isolation and return losses at the frequency range between 1.6 GHz and 2.2 GHz.
