Abstract

A circuit design of Ultra-Wideband (UWB) transient source based on avalanche transistor is presented in this paper. Under a 20V voltage supply, a 1ns pulse width and 12V maximal amplitude periodic pulse is achieved. Experimental results show the pulse width is 1.2ns and the peak amplitude is 14V.In addition, the signal waveform is simple, and the energy mainly range from 600MHz to 2GHz, which are fit for the Ground Penetrating Radar(GPR) application. By easily connecting with low noise amplifier and horn antenna and then testing this whole system, it shows a good performance with a stable and symmetrical waveform. Due to all these advantages above, the UWB pulse generator circuit design is very appropriate to be integrated in GPR system.
