High power experiment of nonlinear transmission lines system

A high power RF pulse formation system was developed based on ferrite magnetic nonlinear transmission lines with cross-linking elements. The system consisted of a pulse forming line, nonlinear transmission lines and a matched high power load or combined dipole antenna. The pulse forming line was based on a 100 kV high power source and a high power microwave coaxial cable. The pulse width of the output waveform of the pulse forming line was 60 ns and the output voltage of pulse was 35 kV. The output high power pulse was fed into nonlinear transmission. The nonlinear transmission lines connected to the matched load produced a RF pulse of 31 kV peak to peak voltage amplitude and with a 308 MHz centre frequency and 13% 3-dB bandwidth. A 380 MHz centre frequency and 12% 3-dB bandwidth were obtained when the nonlinear transmission lines were connected to a combined dipole antenna.
