Low power, fully differential SiGe IR-UWB transmitter and correlation receiver ICs

In this paper a 3.1-10.6 GHz impulse-radio ultra-wideband (IR-UWB) transmitter and a receiver front-end are presented. The transmitter comprises a differential impulse generator mounted chip-on-board on a dipole fed circular slot antenna. It has a low power consumption of 6.6 mW at 200 MHz impulse repetition rate. The receiver front-end, mounted at the feed-point of another dipole antenna, is realized with a fully differential low noise amplifier, an analog multiplier-based correlator and a template impulse generator. The measurement results show a motion tracking capability in the mm range.
