Automotive 77GHz radar chip suits emerging long-range applications

ST has delivered over 35m 24GHz radar transceiver ICs to date, and continues to build its customer base as more and more markets demand vehicles enhanced with ADAS. Today's most developed markets are ready for next-gen features like high-speed adaptive cruise control that require high-power-output, long-range radar, which is best implemented using 77GHz technology. The higher frequency allows smaller antenna sizes and permits the same technology to be used for ADAS requiring short-range, medium-range, or long-range radar, hence simplifying system design and reducing time to market.

ST is now building on its success with 24GHz radar to create a highly integrated 77GHz transceiver that delivers market-leading performance. The device contains three 77GHz transmitters and four receivers on a single chip, which enables customers to build smaller, lower-cost and less complex systems compared with competing solutions in the market that are less highly integrated. The multi-channel architecture of ST's 77GHz radar chip enhances object recognition and resolution that translates into superior performance and dependability on the road.

Marco Monti, Executive Vice President, General Manager, Automotive and Discrete Product Group, STMicroelectronics, said, "We have leveraged our technology and success in ADAS markets to create the industry's most highly integrated 77GHz radar transceiver. Our customers designing-in this device are positioned strongly, as demand for 77GHz technology in advanced markets is growing in mid-market and lower-cost vehicle platforms."

ST is now sampling its multi-channel single-chip 77GHz radar transceiver to lead customers and is preparing to enter volume production in March 2017.
