Abstract
The design of three sections phase velocity taper is put forward in 0.14 THz folded waveguide Traveling Wave Tubes(TWT) research. It can maintain beam-traveling wave velocity synchronization again in output section of interaction circuit and improve the beam operating efficiency. A structure parameter impacting on phase velocity change is found and optimized by slow wave structure dispersion equation. After optimizing design, a large signal program calculation is performed under operating voltage 14.95 kV and current 30 mA. Compared with the structure without phase velocity taper, the efficiency is improved by 9.13％ in 140 GHz, and the output power in improved by 0.84 W. The efficiency is improved by 10.4％ in 142 GHz, and the output power is improved by 0.88 W. -1 dB bandwidth is improved to 7 GHz from 5 GHz. The design improves the bandwidth and beam-traveling wave work efficiency in D band folded waveguide traveling wave tubes.关键词
