Abstract :
A direct conversion receiver for UWB applications operates in 3.1-8.2 GHz and gives a NF of 3.3-4.1 dB and a conversion gain of 52 dB. The chip includes an RF receive chain and a 16 GHz quadrature VCO to generate seven carrier frequencies from 3.4 to 7.9 GHz. The circuit is fabricated in 0.18 μm SiGe BiCMOS process and draws 88 mA from a 2.7 V supply.
