The Ultra-Wide Band technology is the latest radio technology and the significant advancement of wireless communication. The generating and receiving method of UWB signals is one of the key techniques of UWB technology. This paper introduces the realization method of a UWB antipodal modulation generator with LCR (Large Current Radiator) to be driven by H bridge circuit of high speed MOSFETS. Pspices8.0 is used in the simulation and designing of the circuit. The realization method of this circuit is presented in detail. The experiment results show that the pulses generator has the ability to produce nanosecond UWB pulses.
