A single-chip 24 GHz SiGe BiCMOS transceiver for FMCW automotive radars

The design and measured results of a highly integrated FMCW radar transceiver are presented. The transceiver includes a transmitter with +7dBm output power and -82 dBc/Hz phase noise at 100 kHz, dual I/Q receivers with 10dB NF and 18 dB gain, PLL, 15-bit DAC, instrumentation amplifiers, LDO regulators, and a serial programming interface - all designed to operate from -40 to +125degC at 3.5V, 275 mA. Fabricated using Jazz Semiconductor´s 0.18 mum SiGe BiCMOS process and packaged in a 32-pin 5 mm times 5 mm QFN, this RFIC has the highest level of integration at 24 GHz known to the authors.
