Abstract:

In order to realize the Miniaturization of Millimeter Wave(MMW) multilevel solid-state power amplifier，according to the traditional design principles of Wilkinson power divider，this paper presents a Ka-band Wilkinson power divider with chip resistor integrated. The highlight of this design is the use of high precision materials and thin-film technique. Simulation results show that it bears the attributes of low insertion loss，low standing wave，and high isolation in 10 GHz bandwidth. The divider is very small and easy to be fabricated for its simple structure，which is very suitable for the chip-level power synthesis and other miniaturized design of MMW circuit.
