An interference robust receive chain for UWB radio in SiGe BiCMOS

A fully integrated receive chain for UWB radio in SiGe BiCMOS is presented. The packaged device includes a wideband LNA, a mixer, and an IF filter and has an overall NF of 7.5 dB. The IIP3 of -3 dBm and the accurately controlled and steep filter characteristic enables a robust coexistence with systems working in the 2.4 and 5 GHz bands.
