Abstract
A multi-beam triode for RF amplification has plurality of electron beams generated by a thermionic cathode, each electron beam travelling through an associated grid and to a common anode electrode. An input RF energy is coupled to a grid support which is electrically common to a control grid of each electron beam, and RF is coupled out of the grid—anode gap, with suitable input RF matching cavities and output RF matching cavities provided.
