摘要

我们演示了两个匹配的工业加热磁控管的对等锁相操作。两个商用现货加利福尼亚管实验室模型CWM-75L工业加热磁控管被“精心挑选”，具有相同的工作电压(17.5 kV)，电流(5.0 A)，工作频率(915 MHz)和输出功率(75 kW)。它们的微波功率输出通过四端口分支壁定向耦合器和移相器进行交叉耦合。耦合低至彼此输出功率的-20 dB就足以在两个磁控管之间产生互锁操作。这些结果表明，在锁相状态下可以驱动两个以上匹配的磁控管。

Peer-peer phase-locking of two L-band industrial heating magnetrons

We demonstrate the peer-peer phase-locked operation of two matched industrial heating magnetrons. Two commercial off-the-shelf California Tube Laboratory model CWM-75L industrial heating magnetrons were "cherry picked" for identical operating voltage (17.5 kV), current (5.0 A), operating frequency (915 MHz), and output power (75 kW). Their microwave power outputs were cross-coupled by means of a four-port branch wall directional coupler and phase shifter. Coupling as low as -20 dB of each other's output powers was sufficient to create mutual locked operation between both magnetrons. These results suggest more than two matched magnetrons may be driven in a phased-locked condition.
