ABSTRACT:
An integrated N-way Wilkinson power divider is described. In one embodiment, the N-way Wilkinson power divider uses a conductor layer with a cross-over (or cross-under) resistor insulated from the conducting layer by an insulating bridge. In one embodiment, the width of the transmission line underneath a cross-over resistor is adjusted to improve performance In one embodiment, a three-way Wilkinson power divider is formed using microstrip transmission lines on a single-layer substrate that supports the microstrip transmission lines, dielectric insulators, and resistors.
