Abstract :
Generation and simulation of radio frequency ultra wideband signal (RF-UWB) have been presented. RF-UWB signal could be directly synthesized by two streams of Gaussian pulses from corresponding optical pulse shapers. The central frequency and bandwidth of the generated RF-UWB signal are tunable with the utilization of time delay units and attenuators. The power spectral density (PSD) of the generated signal respects the FCC mask.
