摘要：

According to the original design of 30 W level W-band folded waveguide CW traveling wave tube (TWT), a step-tapering structure was at the end of the uniform interaction circuit to improve the electron efficiency. Compared two kinds of tapering circuit, the results indicate that both circuits could achieve over 40W power at 91 GHz similar to 97G Hz. The electron efficiency could be improved from 3% to 4%. A collector design is obtained to improve overall efficiency further, and simulation shows top overall efficiency is 23.6%.
