Investigation of plasma-beam amplifiers with reference to use in communication systems
The quality characteristics of amplification of a plasma travelling wave tube (TWT) are studied. It was shown that linearity, phase stability, the level of combined frequency signals and noise are close to the characteristics of a vacuum TWT. A plasma TWT has higher power and wider range of operating frequency band. A plasma TWT-based power small-sized amplifier is discussed.
