Characteristics of Noise-Modulated High-Power Microwave Amplifiers.
Abstract
This study is primarily concerned with the operation of a high-power traveling-wave amplifier under conditions of multisignal and noise drive. As a result of the inherent nonlinearity of the beam-circuit wave interaction process there exists in addition to harmonic generation, intermodulation products which reduce the available power levels of the fundamental signals. General large-signal one- and two-dimensional multisignal theories are developed for the traveling-wave amplifier using a Lagrangian method of formulation. The results of theoretical investigations for the case of two input signals reveal both a strong larger-amplitude capturing effect as well as a pronounced lower frequency signal preference. Both of these effects have also been observed experimentally using a high-power continuous-wave octave bandwidth traveling-wave amplifier. Similar experimental studies are conducted on a high power continuous-wave wideband crossed-field amplifier for comparison purposes. (Author)
