Texas Instruments AWR2243

Texas Instruments AWR2243 is an integrated second-generation single-chip FMCW transceiver operating in the 76-81 GHz band, designed for demanding automotive radar systems and increasingly deployed in humanoids and mobile robots as a functional-safety sensor. The device combines 3 transmitters (TX 13 dBm), 4 receivers (RX 13 dB NF), an integrated fractional-N PLL, baseband, 45 Msps ADC and MIPI-CSI2 / SPI interfaces in a 161-pin FCBGA 10.4 x 10.4 mm package.

AWR2243 supports cascading of multiple devices to increase channel count (e.g. 12 TX / 16 RX for 4D imaging radar) and provides built-in self-monitoring and interference detection. It is ISO 26262 ASIL-B certified (hardware integrity) with documentation supporting system integration up to ASIL-D, is AEC-Q100 qualified and operates in a junction temperature range from -40 to +140 C. In humanoid robotics it complements LiDAR and cameras under low-visibility conditions (fog, dust, darkness) and detects human presence through non-metallic obstacles.
