A high-definition radar transceiver, the RAA270205 from Renesas meets the calls for of superior driver help methods (ADAS) and autonomous driving (AD) purposes. With 4 transmit and 4 obtain channels, the half helps as much as 16 MIMO channels for top angular accuracy and operates over a frequency band of 76 GHz to 81 GHz.
The RAA270205 was designed in cooperation with Steradian Semiconductors, which Renesas acquired earlier this 12 months. It’s well-suited for imaging radar, long-range forward-looking radar, and 4D radar, however may also be used for nook and central-processing radar architectures. The machine packs an onboard engine for FFT calculation and a 112.5-Msample/s ADC that’s practically thrice quicker than competing units, in line with the producer.
Renesas additionally experiences that the RAA270205’s energy consumption of 1.2 W is 50% decrease than comparable transceivers, and its noise determine of 9 dB is 3 dB lower than different radar transceivers. Additional, the half’s chirp fee of as much as 300 MHz/µs improves radar decision and object detection.
The RAA270205 will likely be accessible in 1Q 2023 in pattern portions, with industrial manufacturing deliberate for 2024. The transceiver is available in a 7.6×5.6-mm embedded wafer-level BGA and will likely be absolutely compliant with automotive trade necessities, akin to IATF 16949, AEC-Q100 Grade2, and ASIL B.
