锁相磁控管模块化设计与仿真验证
Modular design and simulation validation of phase-locked magnetrons
摘要
Abstract
This paper presents a modular multi-magnetron unit design based on the mutual coupling phase-locking scheme,configuring it as an axially output module to address the issue of azimuthal non-uniformity in radial output magnetrons in large-scale array applications and significantly improve system robustness.The magnetrons are connected via phase-locking bridges,and the traditional designs based on single magnetron modules lack flexibility.Additionally,due to the non-uniform azimuthal electric field distribution of radial output magnetrons,adding coupling structures to the phase-locking bridge at different positions causes changes in the characteristic impedance of the magnetrons and alters the proportion of energy in the phase-locking bridge relative to the total system energy,thereby affecting output characteristics and phase-locking efficiency.Initially,various topological structures of magnetron phase-locking units were designed and simulated,showing that the opening position and number of the bridge significantly impact phase-locking performance due to the azimuthal field uniformity.Subsequently,an end-to-end series module,suitable for modular design,was selected for further study,and a four-in-one power combiner was designed based on this structure,making the unit output axially.After power synthesis,the output power of the four-tube phase-locking modular unit reached 988 kW,approximately four times that of a single free-running magnetron,with a phase-locking efficiency of 97%.关键词
