Marx bank pulse circuit based on avalanche transistors can generate high amplitude, high-repetition-rate and low-jitter ultra-wideband pulses. The rising edge of the pulse is determined mainly by the performance of avalanche transistors. The amplitude of the pulse can be adjusted by changing the number of stage and the value of charging capacitors. In this paper, A 25 stages Marx bank pulse circuit is designed and tested, In order to reduce the jitter of the output pulses, an optimized driver circuit is designed and the charging resistors and capacitors are tuned to achieve a higher amplitude. Finally, 2.7 kV peak voltage of the output pulse is obtained, the FWHM is 1 ns, the maximum repetition rate is 10 kHz.
