摘　　要：为满足磁控管微波源在低成本工业、空间无线能量传输系统、超导线性加速器等高功率微波领域的应用,提出基于负载牵引的四路对等磁控管功率合成方法,并开展实验研究。从理论上分析了基于负载牵引的四路对等磁控管功率合成高效合成条件,并通过该方法成功实现基于负载牵引的四路20 kW对等磁控管功率合成系统。测试结果表明,S波段连续波磁控管非相干功率合成系统总功率可以达到57 kW,非相干功率合成效率为85.1%。To meet the application requirement of magnetron microwave sources in low-cost industries,space wireless energy transfer systems,superconducting linear accelerators,and other high-power microwave fields,a power synthesis method for load-pull four-way equal magnetrons was proposed,and then experimented.The condition for high-efficiency power synthesis of four-way equal magnetrons based on loaded pulling was analyzed theoretically,on the basis of which a four-way 20 kW equal magnetron power synthesis system based on loaded pulling was obtained successfully.Test results show that the total power of the S-band continuous wave magnetron non-coherent power synthesis system can reach 57 kW,with a non-coherent power synthesis efficiency of 85.1%.
