Development of a G-band Folded Waveguide Traveling Wave Tube with Peak Power 60W Bandwidth 6GHz
2021
In present work, we report a terahertz (THz) travelling wave tube (TWT) with two cascade sections, which has high power and broad-bandwidth. The operation voltage and operation current of electron beam are 17.18 kV and 71 mA, respectively. Using such electron beam, the peak power of TWT is 60 W at the frequency of 0.22THz. Besides, the gain is over 30 dB at over 6 GHz bandwidth. Such new THz TWT will be applicated in long-range radar and high-speed communication systems.
