基于场效应管与阶跃恢复二极管的皮秒级脉冲源设计
Design of picosecond pulse source based on MOSFET and step recovery diode
摘要
Abstract
As the existing pulse source can not balance pulse width and amplitude,a scheme of based on field effect transistor (MOSFET) and step recovery diode (SRD) combined with picosecond pulse source was put forward.Analyzing traditional designs of several pulse sources,we designed a high repetition rate picosecond pulse generator of 100 volt level and made a design simulation with PSPICE and developed the pulse source PCB board.Measurement shows 2 MHz repetition rate,half amplitude width 400 ps around,range above 110 V and stable waveform.The scheme providedes a new selection for high resolution UWB detection radar transmitter.关键词
