Scientists at Japan's Institute of Science Tokyo have developed a 0.24 mm² radar-on-chip prototype targeting 6G sensing and communication integration. This ultra-compact Frequency-Modulated Continuous-Wave (FMCW) radar chip operates at 9.8 mW, making it ideal for edge devices and IoT applications.

It features a self-linearized synthesizer architecture, achieving 1 GHz bandwidth with sub-0.1% error at 9.7 GHz. The chip supports Integrated Sensing and Communication (ISAC) systems, expected to play a key role in smart cities and industrial automation. It is set to be showcased at the 2026 IEEE ISSCC in San Francisco.
