Abstract

An E-band 70W continuous wave folded waveguide TWT (CW FWTWT) was designed and fabricated. The measured results showed that beam transmission was over 98% at dc and better than 97% at the highest peak RF power. Measured output powers are higher than 76.7W with saturated gains higher than 31.1dB within frequency range of 81-86GHz. This TWT adopts single depressed collector and the total efficiencies are higher than 26.7% within 81-86GHz.

e波段连续波折叠波导行波管的研制

设计并制作了一种e波段70W连续波折叠波导行波管。测量结果表明，在直流时，光束透射率超过98%，在峰值射频功率下，光束透射率优于97%。在81-86GHz频率范围内，实测输出功率大于76.7W，饱和增益大于31.1dB。该行波管采用单抑制集电极，在81 ~ 86ghz范围内总效率高于26.7%。
