采用固态放大器直接驱动前向波管的新型放大链与“固态-中功率行波管-前向波管”三级放大链相比较,具有更好 的性能指标,可靠性指标也将大大提高,由于不需要灯丝预热,可实现放大链的瞬时开机。文章介绍了一种用固态放大器直 接驱动直流工作的S波段前向波管的实验情况和实验数据,对这种新型放大链的技术关键和应用前景进行了分析。
The new amplification chain that directly drives the forward wave tube by the solid state amplifier has better performance indexes and the reliability index will be greatly improved compared with the three-stage amplification chain of “solid-medium-power traveling wave tube-forward wave tube” As the filament does not need preheating, can realize the instantaneous power-on chain. In this paper, we introduce the experimental and experimental data of the S-band forward-wave tube that directly drives the DC with a solid-state amplifier, and analyze the technical key and application prospect of this new type of amplification chain.
