摘　　要：更高的工作频率和更大的输出功率是当前行波管发展的主要方向。为满足Ku波段行波管日益提升的大功率和高效率发展需求,本文在分析慢波结构参数对色散和互作用阻抗影响的基础上,开展了Ku波段环圈慢波结构高功率行波管研究。研究显示,在12.8 kV和0.4 A的工作条件下,环圈行波管可以提供2672.9 W的峰值输出功率,对应的增益和电子效率分别为51.26 dB和26.10%,瞬时3 dB带宽达到2.5 GHz(14~16.5 GHz)。Higher operating frequency and lager output power are currently the main development direction of traveling-wave tubes(TWTs).To meet the requirements of high efficiency and high output power for Ku-band TWTs,a high power TWT based on the ring-loop slow-wave structure(SWS)is investigated.The influences of dimension parameters on high frequency characteristics of the ring-loop SWS are studied in detail.The calculation results show that,with the beam voltage of 12.8 kV and beam current of 0.4 A,the ring-loop TWT can produce a peak output power of 2672.9 W,with a small-signal gain of 51.26 dB and an electron efficiency of 26.10%.The instantaneous 3 dB bandwidth of it can reach 2.5 GHz(14~16.5 GHz).
