Abstract
The repetitive narrow pulse signal generator with a sub-nanosecond front,high-voltage amplitude,and approximately Gaussian single-cycle waveform is extensively applied in areas such as ultra-wideband detection and electromagnetic compatibility testing.This paper introduces the design of an all-solid-state repetitive pulse generator utilizing a Marx circuit architecture,which incorporates components like mica capacitors,avalanche transistors,surface-mount technology resistors,and inductors.To meet the signal output specifications,the printed circuit board layout and microstrip lines have been optimized.Through fine-tuning the matching circuit element parameters,the generator successfully delivers a unipolar negative pulse signal with a peak value of approximately 1 kV,a pulse width of around 650 ps,a leading edge of approximately 450 ps,and a trailing edge of about 700 ps across a 50 Ω resistive load.The resulting pulse waveform exhibits similar,smooth,and steep leading and trailing edges,achieving a repetition rate of 10 kHz.Both the peak value and full width at half maximum jitters are maintained at less than 10%.关键词
