In this article ,a kind of UWB pulse generating circuit which just takes a macrowave BJT as core component is introduced .As the simulation result shows ,the circuit can generate a 1MHz frequency ,4V amplitude ,1ns bandwidth Gaussian Pulse .As test result shows ,this circuit can generate a pulse which meets the requirements of UWB transmission . Comparing several kinds of technology of UWB signal generating ,the pulse generating by the circuit has bigger pulse ampli-tude and the circuit is lower cost ,simple structure and easy to apply in industrial applications .
