Abstract :
This article presents the design and measured performances of a novel 4:1 unequal dual-frequency Wilkinson power divider. This unequal power divider fulfills a high-dividing ratio Wilkinson unequal power divider simultaneously at two arbitrary frequencies. By proportionally reducing the impedances in both arms at different frequencies, the proposed circuit can be constructed with reasonable characteristic impedances, and therefore is easy to be fabricated. Furthermore, the value of isolating resistor can be flexibly adjusted to an available one. For verification, a 4:1 divider has been designed and measured at 0.9GHz and 1.8GHz. Good experimental performances of the proposed power divider, including a 4:1 power split and a good isolation between the output ports at both frequencies are obtained.
