The broadband generator of stochastic electromagnetic oscillations in a decimetric band of waves lengths with output power ≈ 0,3 W is described. The epitaxial-planar VHF transistors of КТ911 type terminated by ring microstrips are used as an active elements. Electrical and amplitude-frequency characteristics of the generator are given. Spectral characteristics of oscillations were investigated by methods of correlation and phase-frequency analysis. We established, that oscillations have non-regular character with appreciable phases jumps.. The stochastic VHF oscillation with such characteristics will be used for investigation of its transmission, reflection and action on plasma.
