摘　　要：固态器件具有电压低、体积小、成本低的优势,但是其输出功率低、带宽窄。电真空器件具有输出功率高、效率高、带宽宽、寿命长的优势,但是体积大、成本高。具有这两者优点结合的新型放大器是研究人员追求的目标,基于平面慢波结构的带状注行波管就是在这个目标牵引下发展起来的一个新方向。本文综述了2010年到2017年IVEC报道的平面行波管,展现了这类新器件的发展路径,以期为该类行波管的未来发展指明方向。Solid-state devices have advantages of low operation voltage,small volume and low cost,but their output power is low and the working frequency band is narrow.Vacuum electron devices have advantages of high output power,high efficiency,wide bandwidth and long life,but the volume of them is large and the cost is high.Amplifier owing both above advantages is the goal pursued by researchers,and the planar traveling wave tube is a new developing direction under this goal.This paper introduces the planar traveling wave tubes reported by IVEC from 2010 to 2017,which reveals the development path of these new devices,so as to point out the direction for the future development.
