Renesas Electronics Corporation, a supplier of semiconductor solutions, is entering the automotive radar market with the introduction of a 4x4-channel, 76-81 GHz transceiver designed to meet the requirements of advanced driver assistance systems (ADAS) and Level 3 and higher autonomous driving applications. Leveraging automotive expertise accumulated through years of global customer engagements, Renesas will incorporate the new RAA270205 high-definition radar transceiver into its growing sensor fusion portfolio, which combines radar, vision systems and other sensing modalities.

The new transceiver monolithic microwave integrated circuit (MMIC) is especially 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 “satellite” automotive radar systems. Equipped with 4Tx and 4Rx channels, the RAA270205 supports up to 16 multiple-input and multiple-output (MIMO) channels. It can be cascaded to enable higher channel count and better radar resolution.

The RAA270205 features best-in-class accuracy with up to 5 GHz of bandwidth, and a 112.5 MSPS ADC (analog-to-digital converter) sampling rate that is nearly three times faster than competing devices. Power consumption of 1.2 W is 50% lower than comparable transceivers and it delivers a noise figure of 9 dB, which is 3 dB less than other radar transceivers. Its superior chirp rate of up to 300 MHz/µs improves radar resolution and object detection.
