Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a Marx circuit high-frequency and high-voltage picosecond pulse generator adopting an avalanche triode serial-parallel structure and its application. Background technique [0002] Picosecond pulses have attracted extensive attention from researchers at home and abroad because of their excellent properties such as rich ultra-wideband spectrum, high temporal and spatial resolution, small signal distortion, excellent directivity and fine controllability. Therefore, it is widely used in many technical fields such as detection radar, biomedicine, low-temperature plasma, food safety, sewage treatment, and high-power microwave. As the device basis for all research, it is imminent to develop a picosecond pulse generator that is all-solid-state, compact, miniaturized, and has high repetition rate, high stability, long life, convenient operation, and economical applicability. Among them...
