Energy doubler for high power microwave pulse compression

摘要:

为了实现高功率微波初级波源的小型化，获得更高功率的输出微波脉冲，研制了用于高功率微波脉冲压缩的能量倍增器。利用了快速反转开关，实现了功率的瞬时放大。实验结果表明在输入微波功率达到5.3 MW时，输出脉冲功率可以达到35 MW，输出峰值功率增益达到7 dB。在这基础上对PM–AM技术进行了研究，并通过该技术获得了平顶的输出微波脉冲，以满足不同实验对初级波源的需求。

Abstract:

The Energy doubler for HPM pulse compression was developed to implement miniaturized source of high power microwave. Using the Phase Shift Keying(PSK) switch, output power, which was higher than input power, could be obtained. It could output 35 MW when the input of peak power was 5.3 MW. The power gain could reach 7dB. In order to obtain the straight top waveform, some researches were done on the technology of PM–AM. These results can satisfy the requirements of miniaturized sources of high power microwave in different experiments.
