Renesas Electronics (TSE: 6723), a global semiconductor solutions provider, today announced its entry into the automotive radar market with a new 4x4-channel, 76-81 GHz radar transceiver, the RAA270205. Designed to meet the demanding requirements of ADAS (Advanced Driver Assistance Systems) and L3 and higher level autonomous driving applications. Leveraging the automotive expertise gained from years of working with customers around the world, Renesas has incorporated this radar transceiver into its growing sensor fusion portfolio, which includes radar, vision systems and other sensing units.
The RAA270205 will be unveiled at electronica in Mu nich, Germany, from November 15-18, 2022, as the result of a design collaboration between Renesas and recently acquired Steradian Semiconductors Private Limited. The new transceiver MMIC (monolithic millimeter wave integrated circuit) is suitable for imaging radar, long-range forward-looking radar and 4D radar, as well as for corner radar and central processing radar architectures, so-called "satellite" vehicle radar systems. MIMO (multiple input and multiple output) channels. It can be cascaded for higher channel counts and better radar resolution.
The RAA270205 offers best-in-class accuracy with a bandwidth of up to 5 GHz, and its 112.5 MSPS ADC (analog-to-digital converter) sampling rate is nearly three times faster than other products in its class. At the same time, the 1.2W power consumption is 50% lower than comparable transceivers. In addition, the product noise coefficient of 9dB, 3dB lower than other radar transceivers. up to 300MHz/µs tuning frequency to enhance the radar resolution and object detection capabilities.
Today's radar transceiver MMICs must achieve higher resolution to support the high precision requirements of ADAS and autonomous driving safety platforms," said Vivek Bhan, senior vice president and vice president of the Automotive Solutions Business Unit at Renesas Electronics. Working closely with Steradian, which has deep radar design expertise, and focusing on features such as functional safety and low power consumption, Renesas is expanding its sensor fusion offerings to help our customers reduce development costs and time-to-market."
