In order to meet the requirement of ultra-high repetition frequency pulse generation in current ultra-fast pulse generation technology, this paper proposes a high repetition frequency reconfigurable pulse generation method based on solid state semiconductor switching technology, pulse power synthesis technology and picosecond high precision delay trigger control technology, and develops a prototype device of high repetition frequency reconfigurable pulse generator with kV/ MHz. The test results show that the pulse generator can stably output sub-nanosecond pulses with amplitude 1 kV, repetition frequency 1 MHz, rise time 700 ps. By precisely adjusting the trigger time sequence of each pulse, the rise time, pulse width and waveform can be flexibly changed, and the repetition frequency can be adjusted from 1 MHz to 50 MHz. It can effectively meet the application requirements of electronic countermeasures, ultra-wideband detection and communication industries.
