Abstract and subjects

Ceramics Copper Couplers dielectric traveling-wave tube Electron tubes high bandwidth Ka-band Radio frequency Welding
We have fabricated a Ka-band dielectric loaded traveling-wave tube with high instantaneous bandwidth of 10GHz centered at 33.25GHz. The process of fabrication involves copper and ceramics machining and several hierarchical assembly steps. We report on the fabrication steps and RF system design. We are currently doing cold-test of the TWT using network analyzer and Ka band signal source.
