Abstract

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.
