The invention relates to a microwave field of electronics and physics, it is used to generate broadband noise signal low and medium capacity and can be used to generate microwave radiation generators. The technical result achieved in the proposed broadband noise microwave oscillator oscillations with a radial turbulent converging electron beam is to increase the efficiency of the device and increase in generation of the strip. Said technical result is achieved in that sverhnizkovoltny generator broadband noise microwave oscillations with a radial converging turbulent electron beam comprising coaxially disposed in the cylindrical housing hollow cylindrical cathode, within which is located a hollow cylindrical anode and a system of microwave radiation output according to the decision, the anode is made in a spiral shape, coaxially located within the anode collector-reflector, the anode is connected to the microwave output system configured as a coaxial second transmission line, wherein the anode and the collector-reflector mounted with clearance, intended to form a turbulent electron beams.
