Abstract The investigation of injection locking of cooker magnetron by a solid-state microwave power source is reported. Experimental results show that a 2.45 GHz cooker magnetron can be locked in continuous wave operation. In the frequency-locking bandwidth, the magnetron output frequency can be tuned by adjusting the injection source. The maximum frequency-locking bandwidth of 12 MHz and noise of less than −60 dBc at a 10 kHz offset frequency are observed. Cascaded locking of multiple magnetrons is also reported. The cascaded magnetrons show the same spectrum characteristics as the solid-state microwave power source and good phase stability, which leads to high efficiency in a power combining experiment.

固态微波电源磁控管注入锁定和级联锁定的研究

摘要 报道了一种固态微波电源对炊具磁控管注入锁定的研究。实验结果表明，2.45 GHz 电磁炉磁控管可以锁定在连续波操作中。在锁频带宽内，磁控管输出频率可通过调节注入源进行调谐。观察到 12 MHz 的最大锁频带宽和在 10 kHz 偏移频率下小于 −60 dBc 的噪声。还报告了多个磁控管的级联锁定。级联磁控管显示出与固态微波电源相同的频谱特性和良好的相位稳定性，从而在功率组合实验中具有很高的效率。
