A multi-channel RX for automotive radar applications at 76.5GHz is presented. The chip uses a LO input signal at 38.25GHz which is multiplied on chip. The single-ended IF outputs show a noise density of -143dBm/Hz at 100kHz with a typical conversion gain of 18dB. The large signal IF channel-to-channel isolation is > 55dB. The 14mm 2 chip consumes 520mA from +3.3V supply in a 200GHz f T SiGe BiCMOS process.
