A Novel Design of Compact Out-of-Phase Power Divider With Arbitrary Ratio

In a conventional power divider, power dividing network and isolation network are usually independent of each other. To reduce the size of out-of-phase power divider with arbitrary power ratio, coupled microstrip lines are proposed to facilitate power dividing and isolation of a power divider simultaneously in this article. Formulations have been derived for the proposed out-of-phase power divider with arbitrary ratio. Two compact power dividers are implemented on the printed circuit board (PCB) with power ratio k

= 9 and k

= 1000 . It can be observed that there is a satisfactory agreement between the simulated and measured results.
