摘要： Disclosed are a solid-state microwave source and a branch consistency control method thereof. The branch consistency control method includes: collecting phase information of each branch unit under each of a plurality of preset target powers, and performing phase adjustment for each branch unit based on the phase information under each of the target powers; assembling coarsely-adjusted N branch units, a driver module, a power distribution module, a radial combiner, a circulator, and a waveguide coupler; adjusting a branch power by using the driver module and the power distribution module, to collect the phase information of each branch unit under each of the target powers; and when the phase information of each branch unit under each of the target powers meets a preset condition, performing phase adjustment for the branch unit based on the phase information.

摘要： Disclosed are an impedance matching apparatus and method for a solid-state microwave source. The impedance matching apparatus is connected to a solid-state microwave source and includes a detection module and a control module. The control module includes a frequency control unit and a power determining unit. The frequency control unit is configured to adjust a current frequency of a phase-locked source of the solid-state microwave source according to a received frequency modulation (FM) instruction. The power determining unit is configured to perform following steps: controlling a driver module of the solid-state microwave source to gradually increase a total incident power, and determining a change trend of a total reflected power of the solid-state microwave source; controlling the driver module to reduce the incident power; setting the FM instruction, and sending the set FM instruction to the frequency control unit.
