Hello, dear colleages!
As we know the impedance of quarter wave line in one stage Wilkinson Power Divider (WPD) is equal to sqrt(2)*Z0. But how to calculate the line impedances for two-stage WPD?

Best regards.

Hi, one of the important parameter for multistage wilkinson power divider is the bandwidth (ratio: f2/f1) you want to realize. And impedance of the quarter wave-lines depend on this ratio. For a two-stage WPD, you can realize bandwidth ratio of either 1.5 or 2.

Go through the below paper for more details:
