摘要: 利用基于SOS的固态脉冲功率源进行了Ka波段相对论返波管振荡器（RBWO）的实验研究。该固态脉冲功率源工作电压200～360 kV,工作电流约2.6 kA,脉宽约20 ns,脉冲上升前沿约9 ns。SOS固态脉冲功率源驱动Ka波段BWO的实验结果为：微波频率36～38 GHz,脉宽约10 ns,峰值功率约50 MW,重复频率10 Hz。Abstract: This paper reports the experiment of a Ka-band relative backward wave oscillator(RBWO) driven by the all-solid-state pulsed power generator based on semiconductor opening switch. Under working voltage of 200～360 kV and current of 2.6 kA, the generator’s output is about 20 ns in pulse width with rise time less than 9 ns. The experiment show that Ka-band RBWO can generate microwaves with peak power about 50 MW, frequency 36～38 GHz, pulse width about 10 ns, and repetition rate 10 Hz。
