  • Abstract
    A dynamic velocity taper (DVT) characterized by exponential taper pitch have been designed for high efficiency millimetre wave TWT. Design result in K and Ka band shows a great improvement of electron efficiency. The experimental results can reach 23% in Ka band and 25% in K band TWT.
