Abstract

This paper presents a 76- to 81-GHz transceiver chipset implemented in SiGe BiCMOS technology for both long-range and short-range radar applications. A four-channel receiver achieves 11-12 dB noise figure, 16-dB conversion gain, and -2 dBm input compression point. A single-channel transmitter with integrated subharmonic VCO achieves +17 dBm output power and -97 dBc/Hz phase noise at 1-MHz offset referenced to the 77-GHz carrier. The chipset includes built-in-self-test features allowing measurement of RF power, gain, and phase. Total power consumption is 0.79 W for the four-channel receiver and 1.16 W for the transmitter.
