摘要
Abstract
Based on an ultrashort H-plane coupler and a cut-off structure,a high frequency structure of a W-band Periodically Cusped-Magnetic(PCM)field focused wideband sheet-beam Traveling-Wave Tube(TWT)is shortened by 27.7 mm.This approach allows the TWT to generate more than 200 W of power within a bandwidth of 13 GHz(90～103 GHz).The interaction between the electron beam and microwave in the ultrashort cut-off structure is investigated.The study shows that the ultrashort cut-off structure can mitigate the divergence of bunched electrons at the cut off structure when the first section of the Slow-Wave Structure(SWS)is long enough,thereby significantly enhancing the output power and bandwidth of the TWT.Therefore,long cut-off structures,high input signal voltages,and low electron gun voltages should be avoided when a wideband TWT is designed.关键词
