Design of Miniaturized Unequal Split Wilkinson Power Divider with Harmonics Suppression Using Non-Uniform Transmission LinesAbstract
In this paper, a design of an unequal split Wilkinson power divider (WPD), with high power split ratio, using non-uniform transmission lines (NTLs) is presented. The design is based on using NTLs in each branch of the divider instead of the conventional uniform ones. Besides the achievement of high power split ratio, the size of the designed WPD is reduced. The design procedure is presented for arbitrary design frequency and arbitrary power split ratio. For verification purposes, a 10:1 WPD is designed and fabricated. Good isolation between the output ports, input/output ports matching, and transmission responses are achieved at the design frequency. The experimental and full-wave simulation results show the validity of the designed NTL-WPD. Compared to the conventional design, it is noticed that the proposed divider is more likely suitable for narrowband applications.
