Abstract

In this paper, a new N-way multi-frequency unequal split Wilkinson power divider (WPD) is proposed. The dividers are composed of multi-section transmission line transformers (TLT) and isolation resistors, which provide high isolation and very good input/output ports matching simultaneously at arbitrary design frequencies. To verify the validity of the design, several multi-frequency power dividers are designed and simulated. Specifically, a 3-way unequal split dual-frequency WPD operating at 900 and 1800 MHz, a 3-way unequal split triple-frequency WPD operating at 1, 2, 3 GHz, and a 4-way equal split quad-frequency WPD operating at 1, 2, 3, 4 GHz, are designed.
