A novel radar frontend for 77 GHz mid-range-radar (MRR) and short-range-radar (SRR) applications is presented. The radar sensor makes use of a Colpitts oscillator, frequency multipliers, and a transceive (TRX) mixer. A single sensor contains up to four channels using antenna arrays for angular detection relative to the sensor. The characterization of the integrated circuit's parameters has been carried...

A fully integrated 4-channel automotive radar transceiver chip, integrated in a 200-GHz SiGe:C production technology, is presented. With a typical transmit power of 2 x +7 dBm at the antenna ports and all functions active, the chip draws a current of about 600 mA from a single 5.5 V supply. The design permits FMCW operation in the 76 to 77 GHz band at chip-backside temperatures from -40degC to +125degC.
