This article presents a low‐cost ultra‐wideband (UWB) pulse generator that is built using commercially available discrete components mounted on a PTFE substrate. A novel pulse shaping technique is adopted, which uses Schottky barrier diodes to generate a Gaussian‐cosine pulse with desirable time duration and spectrum response. Generated baseband pulses then are up‐converted to a center frequency of 4 or 8 GHz by a passive mixer, and Binary Phase‐Shift Keying (BPSK) modulation scheme is utilized. The final generated pulse with a bandwidth (−10 dB) of more than 1 GHz satisfies the FCC spectrum mask very well without any extra filtering, and can operate in either 3.1–5 GHz low band or 6–10 GHz high band. © Wiley Periodicals, Inc.
