High Power Division Ratio Dividers for Millimeter- Wave Applications

A novel power divider which can provide a high power division ratio is presented for millimeter-wave applications. Similar to conventional non-equal Wilkinsondividers, it consists of two section transmission lines (TL) with different characteristic impedances and one isolation resistor. But, a round inductor is used to make the high impedance TLimplementable in MMIC fabrications. A 60 GHz divider with a large power-dividing ratio (1:9) has been designed and simulatedin a standard 130 nm GaAs process. The results show that the structure can effectively be used as an arbitrary power division ratio divider.
