Introduction

The IWR6x43 device is an integrated single-chip millimeter-wave sensor capable of operating in the 60GHz to 64GHz frequency band and based on FMCW radar technology. This device is manufactured using TI's low-power 45nm RFCMOS process and achieves excellent integration in an ultra-small package. It is an ideal solution for low-power, self-monitoring, and ultra-precise radar systems in the industrial field. Currently, multiple models are available, including devices compliant with functional safety standards and non-functional safety devices.
