D3 Engineering Automotive-Grade mmWave Radar Sensor Integrates Antenna Array in 1” Package
December 24, 2020
The RF front end integrates a PLL, three transmitters, four receivers, and baseband ADC, and allows the sensor to cover up to 4 GHz at a 12 dBm transmit power.
D3 Engineering has announced the DesignCore RS-6843AOPUA mmWave Radar Sensor, an AECQ-100-qualified 60 GHz radar device that integrates a Texas Instruments C674x DSP, Arm Cortex-R4F MCU, radar accelerator, and on-package antenna array. The RF front end integrates a PLL, three transmitters, four receivers, and baseband ADC, and allows the sensor to cover up to 4 GHz at a 12 dBm transmit power and noise characteristics of better than 15 dB.
The 1” x 1” x 1” sensor is a production-intent device that features a heat-spreading metal body and mounting tabs. It can be tested and evaluated over a USB-Serial interface, and used with a PC or embedded development platforms.
The sensor is available in two versions:
- RS-6843AOPA – Features a header with additional functionality and interfaces such as I2C, SPI, GPIO and UART for connection to optional baseboards or hosts.
- RS-6843AOPUA – Uses a USB-C connector as the primary interface, which provides power as well as one serial UART for console and another for processed radar returns or algorithmic outputs.
Custom firmware on the sensors ensures board support for the latest T.I. SDK. The DesignCore RS-6843AOPUA is available for pre-order now.
