The invention discloses an intracavity light-operated microwave power combiner, which relates to the technical field of high-power microwave and particle accelerators, and comprises a combiner shell which comprises a microwave signal source, a laser light source, an electro-optical modulator and a cavity light-operated microwave power synthesis module. The cavity light-operated microwave power synthesis module is composed of an optical beam splitter, an optical phase shifter array, a photoelectric converter array, a solid-state amplifier array and a coupling cavity, a microwave signal is loaded on an optical signal emitted by a laser through an electro-optical modulator, and signal light loaded with the microwave signal is divided into m sub-paths through the optical beam splitter, and each sub-path microwave signal respectively passes through an optical phase shifter to realize phase control of the signal. According to the scheme, in-cavity microwave power synthesis of solid-state amplifier array microwave signals is achieved through the light-operated phased array method according to the requirements of particle accelerators and the like for in-cavity high-power microwaves, and high-power microwave output is achieved.
Description
technical field [0001] The invention relates to the technical fields of high-power microwaves and particle accelerators, in particular to an optically controlled microwave power combiner in a cavity. Background technique [0002] Microwave power synthesis refers to the technology of combining the output power of multiple oscillation sources in order to improve the output power of microwave solid-state oscillators. The main method used is to install multiple oscillation diodes in the same microwave resonant cavity to realize the Synthesis of output power, or coupling multiple oscillators through various forms of external circuits for power synthesis.
