【Abstract】 This paper reports the design,simulation work and test results of a Ku-band 150 W continuous wave space Traveling Wave Tube(TWT),which is fulfilled at the Institute of Electronics,ChineseAcademy of Sciences.The double-anode gun,helix pitch-tapering slow wave structure,non-axisymmetric four-stage depressed collector and radiation-cooled radiator are used in this TWT. The test results indicate that in the case of saturated drive,the TWT can get a power of over 154 W,an efficiency of over 62%,a gain of over 51. 8 dB,a phase shift less than46. 65°,and AM /PM factor less than 4. 31 deg /dB with the beam transmission rate of over 98. 5% in the operation band of 12. 25 ~ 12. 75 GHz. The environment testing was performed and the results show that the configuration design of this TWT is satisfiedfor a satellitemechanicsenvironment and the heat dissipation design is satisfied for an airborne environment.更多还原
