Description

technical field [0001] The present invention relates to a waveguide power combiner, more specifically, to a millimeter wave waveguide power combiner. Background technique [0002] The millimeter wave power output device is one of the core devices of the millimeter wave system. Traditional vacuum electronic devices such as klystrons and traveling wave tubes still play an important role in many fields with high power requirements due to their high efficiency and high power output capabilities in the millimeter wave frequency band. Vacuum electronic devices can output large power, but they have disadvantages such as high operating voltage, low reliability, and short life. Millimeter-wave solid-state devices have the advantages of low operating voltage, high reliability, and long life, and have attracted much attention from researchers. The rapid development of semiconductor and computer simulation technology has promoted the development of microwave and millimeter wave solid-...
