A 79GHz SiGe-Bipolar Spread-Spectrum TX for Automotive Radar

A 79GHz spread-spectrum TX, implemented in a SiGe bipolar process, consists of a VCO, a prescaler, a PRBS generator, and a biphase modulator. The sequence length of the PRBS is 1023 bits at a bit rate of 1.235Gb/s. The chip provides an output power of -1dBm and draws 750mA from a 5.5V supply
