Researchers at Japan's Institute of Science Tokyo have created a 0.24 mm² radar-on-chip prototype designed for 6G applications, consuming only 9.8 mW of power. This Frequency-Modulated Continuous-Wave (FMCW) radar generator integrates sensing and communication, suitable for edge devices and IoT.

The chip achieves a 1 GHz bandwidth with sub-0.1% error at 9.7 GHz. It will be presented at the 2026 IEEE ISSCC in San Francisco, with potential applications in automotive safety, robotics, and wearables.
