Effective transformation of high voltage power into high frequency oscillatons based on transmission line with saturated ferrite

Summary form only given. New method of high voltage power transformation into high frequency oscillations in the coaxial line with temporal dispersion is investigated. Temporal dispersion is due to pulsed magnetization switching of initially saturated with axial bias field ferrite. Pulsed magnetic field is created by high voltage nanosecond pulse propagating through the nonlinear transmission line. Subnanosecond rise time excites damped oscillations of circumferential component of magnetization and pulsed current. Effect of microwave power amplification with nonlinear transmission line elongation has been detected. Developed system seems to be an alternative to the nonlinear transmission line with spatial dispersion. For 9 ns pulse efficiency of about 10 % has been achieved. Possibility of oscillations excitation at frequencies from 600 MHz to 1.1 GHz with bandwidth of about 15 % for pulse amplitudes from 110 to 290 kV is shown. Optimal bias field conditions are found to be in the range 20-40 kA/m.
