Summary:A 60GHz Doppler radar for short-range presence detection applications in the unlicensed 60GHz band is described. The 1.1times2.1 mm 2 SiGe:C BiCMOS IC includes a 60GHz VCO, a polyphase filter for quadrature signal generation, a low-noise amplifier with current reuse quadrature down-conversion mixer and a power amplifier. The VCO can be tuned from 59.5-61.5GHz. The receiver quadrature accuracy is better than 27dB across a plusmn10MHz IF bandwidth. With a single-ended input drive of the differential input, the receiver achieves a conversion gain of 55dB and a DSB noise figure of 22.9dB. Assuming 4dBi antenna gains, the radar IC supports up to 5m range.
