Sources of intensive mm noise oscillations based on BWO

In this paper a method of creation of millimeter random signal sources using dynamic properties of backward wave oscillators is considered. Causes are studied to be prevented from realization of the great values of working-current to starting- current ratio for this band. Using of the low-quality factor oscillatory systems for effective interaction increase is proposed. Peculiarities of chaotic oscillation extension in weak-resonant BWO are studied and the technical specifications of the designed random oscillation sources of millimeter wave band are presented.
