A new method of broad-band microwave signals creation by means of amplitrons was proposed and realized. It was shown that the intensive axial space charge oscillations should appear for multy-frequency output spectra formation in devices of such type t was reached under the "percussion" action of high amplitude RF fields at the frequencies from the range of own electron cloud auto-osciHations frequencies. These fields were created at the end of interaction space. The source of high power (up to 100-120 kW) and wide-band (more than octave) quasi-chaotic microwave radiation was realized on the base of investigated amplitron.
