| Abstract: | The Ultra-Wideband(UWB) technology is introduced in this paper.The circuit was fabricated on microstrip line.An ultra-short pulse is achieved which duration was around in the order of 1ns,repetition rate was 100MHz.The design of the circuit especially the tuning of the basing and matching circuit is analyzed and discussed.Measured results show that the waveform of pulse if good,and the ringing level is low.The pulse generator will find applications in UWB communications system. |
