Abstract
A hybrid millimeter-wave Wilkinson divider comprises an input port (), a first output port (), a second output port (), and transmission lines connecting the input port () to the first and second output ports () implemented by transmission lines in a carrier substrate (PCB,). An isolation resistor of the Wilkinson divider connected between the first and second output ports () is integrated in a monolithic micro-wave integrated circuit (MMIC) chip () installed on the carrier substrate. On the MMIC chip the isolation resistor is connected between RF input metal pads. A compensation circuit for parasitic capacitances caused by the RF input metal pads is provided on the MMIC chip () so that the on-chip resistor appears as a pure resistance to the output ports () of the Wilkinson divider on the carrier substrate (PCB,).
