摘要
注入锁频是磁控管相干功率合成的基础,本文开展了15 k W磁控管的注入锁频实验,研究了注入微波功率与可牵引带宽之间的关系。实现了15 k W磁控管注入锁频,分析了不同注入功率下磁控管可牵引带宽。实验结果表明,磁控管注入锁频牵引带宽随注入功率增大而增加,在165 W注入功率下牵引带宽达到5 MHz。该15 k W磁控管可用于大功率微波相干功率合成,为多支大功率磁控管进行功率合成研究奠定了基础。
Injection phase-locking is the basis of microwave coherent power combining between magnetrons. The experiments of injection locking on a 15 k W large power S-band magnetron and the relation between the injection power and locking bandwidth are presented.The experimental results show that the 15 k W S-band magnetron achieves the phase-locking successfully. The locking bandwidths under various injection powers are studied.The experimental results show that the locking bandwidth becomes wider with the increase of injection power. The locking bandwidth reaches 5 MHz while the injection power is 165 W.It shows that the 15 k W magnetron is a powerful candidate for large power coherent power combining. The study lays the foundation of power combining between multiple large power continuous wave magnetrons.
