[Abstract]:A picosecond pulse source design scheme based on field effect transistor (MOSFET) and step recovery diode (SRD) is proposed. Based on the research and analysis of several traditional pulse source design schemes, a high voltage picosecond pulse generator with high repetition frequency is designed. The design scheme is simulated on PSpice and the PCB board of pulse source is made. The half-amplitude pulse width is about 400 pss and the amplitude is more than 110 V, and the waveform is stable, which provides a new choice for the design of high resolution ultra-wideband detection radar transmitter.
