Abstract :
Physical principles of designing continuous action BWT type vacuum generators radiating microwave energy simultaneously at several carrier frequencies in a MMD are described. The control of the output level and frequency in every band are considered. The resonance properties of the sections of periodical structures and the focusing of electron beams in an inhomogeneous magnetic field are used in the generators. A description is given of how to excite the amplitude-modulated (AM) oscillations with a high modulation depth factor and small nonlinear distortions. Moreover, the frequency deviation is insignificant. The operating characteristics and output device parameters are given.
