【摘要】：該文對Ka波段空間行波管寬頻帶、高線性、高效率的慢波系統(tǒng)進行設計,通過動態(tài)漸變技術實現(xiàn)了低相位失真、高效率的指標要求。在此設計基礎上研制的Ka波段空間行波管實現(xiàn)了寬頻帶(25~27 GHz)、低非線性失真(非線性相移≤40°,AM/PM≤2.86°/d B,三階交調≥10.39 d Bc)、高效率(總效率≥51.7%)。經(jīng)數(shù)傳系統(tǒng)測試,誤碼P_e優(yōu)于10~(-6)的情況下C/N_0有2.4 d B裕度,滿足了衛(wèi)星數(shù)傳系統(tǒng)對多通道并行傳輸方案的工作需求。
[Abstract]:In this paper, a wide band, high linearity and high efficiency slow wave system of Ka-band space TWT is designed. The requirements of low phase distortion and high efficiency are realized by dynamic gradient technique. On the basis of this design, a Ka-band space TWT has been developed with wide bandwidth (255GHz), low nonlinear distortion (nonlinear phase shift 鈮，
