Abstract

In the experiment, we found that nonlinear photoconductive semiconductor switches (PCSS´s) is triggered by lower energy laser pulse, that ultra-fast electric pulse of 200ps rising time and 500ps pulse width is obtained, and that frequency bandwidth is more than 6.0GHz. The switch and double ridges horn antenna are integrated and the receiving antenna is connected with the oscillograph and frequency analytical instrument using coaxial transmission line.
