Abstract :
As Terahertz communication technology developed, the research for D-band folded waveguide Traveling Wave Tube (FWTWT) has become increasingly important. The design and simulation on the FWTWT was presented, including electron-optical system, Folded Waveguide Slow Wave Structure (FW SWS) and sapphire pill-box window. A prototype tube has been fabricated successfully through manufacturing processing study. In the work duty 100% experiment conditions, the electron transmission ratio is 97%. The continuous wave output power is 7.3W and the center frequency is 140.3GHz. The gain is 25.3dB and 3dB bandwidth is 3GHz.
