Abstract :
We present a 77 GHz four-channel transceiver for automotive radar applications designed in a 200 GHz fT SiGe BiCMOS technology. The chip features a Tx-channel, a prescaler by 1536, and three Rx-channels. One of those Rx is in I/Q configuration. The Rx-channels show a typical conversion gain of 19 dB while the NFssb is lower than 13 dB at 100 kHz. The VCO is based on a new topology which allows generating differential push-push outputs. It shows a tuning range larger than 8 GHz. The phase noise is -74dBc/Hz at 100 kHz offset. The output power is 9 dBm. At a 3.3 V supply, the chip consumes 533 mA.
