摘要

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.
