Design optimization of W-band CW TWT for improving overall efficiency
According to the original design of 30W 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 91GHz~97GHz. 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%.
