- 摘要:
- 本文對220GHz折疊波導慢波電路的返波傳輸特性進行了研究。介紹了返波振蕩器的工作原理，結合模擬仿真和理論分析，針對220GHz的返波振蕩器，研究各個參數對冷特性的影響。對220GHz返波振蕩器的高頻結構進行了初步設計，給出了結構參數以及相應的模擬結果。結果表明在不考慮損耗的情況下，設計的結構可以在中心頻率220GHz處獲得約為0.5W的功率，可調諧范圍是30GHz，調諧電壓范圍為5.5-12kV。
- Abstract:
- In this paper, the backward wave transportation of 220GHz folded waveguide (FWG) circuit was investigated. Focusing on 220GHz backward wave oscillator (BWO), and using theory and numerical simulation methods, research on cold characteristics and design the high frequency structure of 220GHz BWO. The parameters of structure and relevant simulation results have presented. The study shows the BWO can achieve power about 0.5w at 220GHz with considering lossless, and it can tunes fully and rapidly over wide band (~15%)of frequencies by adjusting the beam voltage from 5.5kV to 12Kv.
