Nonlinear Behavior of Transverse‐Wave Amplifiers

摘要

The nonlinear behavior of traveling‐wave amplifiers using transverse interaction modes (cyclotron and synchronous beam waves) is analyzed theoretically. An analytical solution for the circuit field amplitude as a function of distance is derived, under the assumption of a relatively slow growth per wavelength. Detailed calculations of the saturation characteristics (output power versus input power) are presented for several cases, and it is shown how the electronic efficiency can be improved by operating at a beam voltage above the synchronous voltage.
