A 3.1-10.6 GHz ultra-wideband pulse-shaping mixer

This paper presents a mixer for pulse-based ultra-wideband (UWB) communication. Pulses are shaped using a new technique that accurately approximates a Gaussian pulse by exploiting the properties of a BJT. The mixer is fabricated in a 0.18 /spl mu/m SiGe BiCMOS process. Simulation and experimental results are presented.
