摘要：

A W-band 100W three-section folded waveguide traveling wave tube (TWT) is investigated by numerical simulation and fabrication experiments. The results show that the ridge loaded folded waveguide circuit achieves higher coupling impedance than conventional folded waveguide circuit with dispersion characteristics almost unchanged. Three-section structure can not only increase gain and gain flatness of TWT, but also save cost by removing attenuator and improve machining straightness of each section ridge-loaded folded waveguide assembly by shortening length of it.
