Abstract :
A multi-channel RX for automotive radar applications at 76.5 GHz is presented. The chip uses a LO input signal at 38.25 GHz which is multiplied on chip. The single-ended IF outputs show a noise density of -143 dBm/Hz at 100 kHz with a typical conversion gain of 18 dB. The large signal IF channel-to-channel isolation is > 55 dB. The 14 mm2 chip consumes 520 mA from +3.3 V supply in a 200 GHz fT SiGe BiCMOS process.
