Renesas reveals portfolio of radar transceivers

LinkedIn +

Supplier of advanced semiconductor solutions Renesas Electronics will enter the automotive radar market with its 4×4-channel, 76-81GHz radar transceiver which has been developed to meet the requirements of ADAS and Level 3 (and higher) autonomous driving applications.

Renesas plans to incorporate its latest RAA270205 high-definition radar transceiver into the company’s ever-expanding sensor fusion portfolio which combines radar, vision systems and other sensing modalities.

The RAA270205 was designed in collaboration with Steradian Semiconductors, a company Renesas acquired earlier in 2022.

The new transceiver monolithic microwave integrated circuit (MMIC) is suited for imaging radar, long-range forward-looking radar and 4D radar, but can also be used for corner and central-processing radar architectures. The RAA270205 solution benefits from 4Tx and 4Rx channels and supports up to 16 multiple-input and multiple-output channels.

The RAA270205 features up to 5GHz of bandwidth and a 112.5MSPS analog-to-digital converter sampling rate which is stated to be nearly three times faster than other devices available on the market today. Additionally, the solution delivers a noise figure of 9dB and a chirp rate of up to 300MHz/µs to improve radar resolution and object detection.

“Today’s radar transceiver MMICs must achieve higher definition to support the high-accuracy requirements of ADAS and autonomous driving safety platforms,” said Vivek Bhan, senior vice president and deputy general manager, Renesas Automotive Solution Business Unit.

“Working in close collaboration with Steradian, which brings deep radar design expertise, we are expanding our sensor fusion offerings with a focus on functional safety and low power consumption to help our customers lower their development costs and improve time to market.”
