Highly Integrated and Compact Size FMCW Radar Sensor Optimized for IoT Applications and Healthcare Devices

Infineon Technologies has introduced the new XENSIV 60 GHz radar sensor BGT60UTR11AIP that comes with a compact size of 16 mm² is specifically designed for integration into the smallest devices. This sensor is ideal for vital sensing (heart and respiratory rate) and healthcare devices such as baby monitors and sleep trackers. It is also suitable for consumer electronics such as laptops, TVs and cameras, as well as smart home and building devices such as air conditioners, thermostats and smart doorbells. This radar sensor can also be used in industrial applications including robotics and tank level measurement.

The monolithic microwave integrated circuit (MMIC) is based on Infineon’s B11 SiGe BiCMOS technology, which ensures excellent radio frequency (RF) performance. The chip features an ultra-wide bandwidth of 5.6 GHz and a ramp speed of 400 MHz/µs. As a result, the sensor enables high-resolution frequency modulated continuous wave (FMCW) operation with sensitive presence and motion detection at a range of up to 15 m (50 ft). In addition, the sensor enables precise distance measurement, 1D gesture and vital sign detection, all with sub-mm motion detection capabilities. The integrated antennas provide a ±60° field of view.
