STMicroelectronics, a semiconductor manufacturer, also supplying short- and mid-range (24GHz) radar chips for Advanced Driver Assistance Systems (ADAS) announces its new long-range (77GHz) radar chips to automotive clients.

24GHz systems have introduced an on-board automotive radar by enabling short- and mid-range smart-driving features such as blind-spot detection, collision avoidance, and lane-departure warning. ST has delivered 24GHz radar transceivers, and continues to deliver as markets demand vehicles enhanced with ADAS.

Today's developed markets are ready for next-generation features like high-speed adaptive cruise control that require high-power-output, long-range radar, which is 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.

The manufacturer uses 24GHz radar to create an integrated 77GHz transceiver. The device contains three 77GHz transmitters and four receivers on a single chip, which enables customers to build smaller, lower-cost systems. The multi-channel architecture of ST's new 77GHz radar chip enhances object recognition and resolution that translates into steady performance on the road.

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.
