Abstract :
A fully integrated SiGe BiCMOS low noise amplifier (LNA) for ultra-wideband (UWB) has been implemented in a 0.4 μm SiGe BiCMOS technology from Motorola Semiconductors. It features a cut-off frequency of 46 GHz. The LNA exhibits a wide bandwidth, from 3 to 10.5 GHz, with a flat gain of 24 dB. This amplifier shows a noise figure below 4.4 dB over the whole bandwidth and achieves good return losses without any matching network. This 3-10.5 GHz SiGe LNA design meets FCC Part 15 restrictions for UWB technology.
