Problems solved by technology

The main disadvantages of the above two picosecond pulse generators are: due to the limitation of switches and other components, the output picosecond pulse amplitude is limited (the maximum is only 1000V), and it cannot generate high-energy, high-amplitude, and easy-to-adjust repetition frequency. Picosecond pulse signal, which limits the application range of ultra-wideband picosecond pulse
