Development of an S/C Band Miniature Traveling Wave Tubes

Abstract

A new class of S/C Band Miniature Traveling Wave Tubes (TWTs) is being developed for a microwave power module and aero plane that can be used for radar applications. The maximum dimensions of the S/C miniature TWTs, which saturated output is greater than 200 W (53 dBm), and efficiency greater than 30% and harmonic-ratio less than -3dBc, were just 300mm×80mm×40mm.
