A traveling-wave tube, wherein the wire helix of prior art devices is replaced by a digital helix formed within a composite structure of thick or thin film substrates. The traveling-wave tube helix is formed from multiple substrate layers, each having conductive segments surrounded by insulating material. The superimposing of the substrate layers causes conductive segments from adjacent layers to partially overlap and form a continuous slow-wave structure between an input lead and an output lead, that mimics a traditional wire helix. The composite structure creation of the traveling-wave tube helix allows traveling-wave tubes to be miniaturized and increased in efficiency to point previously unachievable by traditional wire helix devices. |
