Study Of High Power Microwave Power Combiner

Power combining technology is one of the important method which can obtain high power microwave radiation. It can enhance efficient radiation power to n times or more over based on the single high power microwave oscillator, so it's meaningful to the development of HPM. There isn't too much power combining reports of HPM at the present time in international. This thesis has studied some key HPM power combining technologies such as phase-locked source, high power phase shifter and high power combiner. According to the facts of HPRL, it presents a combining project of relativistic magnetron with three output ports which acts as an phase-coherent HPM source. Through theoretical computation and HFSS simulation, we have designed the HPM dielectric phase shifter and waveguide-based combiner. At the end, this thesis also has studied some characters of multiple-beam klystron resonator by moment method and the measured result accords with the computed result. A coaxial loaded filter of input resonator also presented in the thesis, the simulation data agrees well with the theoretical data.
