Abstract
A traveling wave tube made in accordance with this invention wherein the folded waveguide interaction circuit and the input/output transitions to standard waveguides are made of a single piece of metal such as oxygen-free, high conductivity copper. By manufacturing the folded waveguide circuit and the input/output circuit-to-standard waveguide transition out of one piece of material, VSWR on the order of 1.1:1 is expected for traveling wave tubes intended to operate at 94 GHz. Furthermore, this invention minimizes expensive tooling and labor while providing a higher yield of traveling wave tubes.
