Abstract :
This paper presents a SiGe BiCMOS transmitter chipset for 24/77-GHz automotive radar sensors. The chipset adopts a dual-band architecture consisting of a 24-GHz section for ultra-wideband short-range radar operation, which is able to drive the 77-GHz long-range radar transmitter front-end. The proposed solution allows using a single 24-GHz frequency synthesizer to implement both operation modes. The 77-GHz transmitter demonstrates an output power of 12 dBm, a power gain of 20 dB and an output-referred 1-dB compression point of 11 dBm, while drawing 155 mA from a 2.5-V supply voltage.
