This paper describes a low-cost architecture for the generation of subnanosecond pulses based on the transient response of passive filters. Two prototypes are developed to demonstrate experimentally this approach. The first one covers the band 1.61 GHz to 10.6 GHz for medical imaging systems and the second one the band 1.99 GHz to 10.6 GHz for through-wall imaging and surveillance systems. In both cases, we obtain pulses with spectral densities well adapted to the FCC rules.
