Even though collision-avoidance radar systems operate at millimeter-wave frequencies at 77 GHz, an increasing number of integrated-circuit (IC) suppliers are finding ways to design and fabricate practical 77-GHz radar transceivers for this fast-growing application. Abstract: This paper presents a 77-GHz radar system using a transmitter (Tx) and receiver (Rx) integrated with on-chip waveguide feeders in 65-nm CMOS. Abstract: In order to meet the demand for mass production of 77 GHz automotive radar systems, a low cost and high performance 38/77 GHz AlGaAs/InGaAs PHEMT MMIC transmit amplifier with a multiplier has been realized. 2x Reliability AEC Q100 Grade 1 AEC Q100 Grade 3 Thickness < 300 um > 500 um Radar Noise Figure 6-7 dB > 20 dB Gain 15 dB < 15 dB. There are even some impulse UWB units available. automotive radar. ADI and Renesas collaborate on 77/79-GHz Automotive RADAR technology Analog Devices and Renesas Electronics are collaborating on a system-level 77/79-GHz RADAR sensor demonstrator to improve Advanced Driver Assistance Systems (ADAS) applications and enable autonomous driving vehicles. Technical details of the radar sensor used in this paper. The advancements in SiGe BiCMOS technology has enabled the mass commercialization of automotive radars working at 24-GHz and 77-GHz bands.
