Summary:
In this paper, simple circuits for ultra-wideband (UWB) pulse generation and radiation using MESFET and BJT are presented. A novel method was investigated to generate the extremely short pulses with fast rise and fall times having a very broad spectrum and appropriate energy content. Circuits terminated resistively as well as by a UWB antenna covering the 3.1-10.6 GHz frequency band are considered. The transient and frequency domain simulations were carried out and it was found that the results conform to most of the FCC’s regulation for UWB systems. The operating principle of the circuits was experimentally verified for a scaled down frequency band.
