A Modified Gysel Power Divider of Arbitrary Power Ratio and Real Terminated Impedances

The Gysel power divider (PD) is modified to achieve unequal or equal power division and suitability for three arbitrary real terminated impedances without any transmission losses in this letter. The calculation of electrical parameters in this asymmetrical structure is flexible. Meanwhile, this modified Gysel PD maintains high power-handling advantage over Wilkinson PD. By using the transmission line theory, the simple closed-form design equations are available for evaluation of these circuit parameters. For verification, two microstrip examples, which include an equal Gysel PD with three different output-port impedances and an unequal one for three standard 50-Ω ports without additional output-port transformers, are given. It can be observed that there is excellent agreement between the simulated and measured results.
