Infineon Technologies introduces the new XENSIV 60 GHz BGT60UTR11AIP radar sensor. With a compact size of just 16 mm², it is the smallest 60 GHz radar sensor with integrated antennas (AIP) on the market and has been specifically designed for integration into the smallest devices.
This makes the sensor ideal for vital detection (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. The 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 has 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).
Additionally, the sensor enables accurate distance measurement, 1D gesture detection, and vital signs, all with sub-mm motion detection capabilities. Integrated antennas provide a ±60° field of view. Additionally, an integrated state machine enables real-time data acquisition without processor interaction. The MMIC also includes a 12-bit analog-to-digital converter (ADC) with a sampling rate of up to 4 MSPS (megasamples per second).
MMIC's integrated transmission mode allows multiple chips to be synchronized. It also includes on-chip sensors to measure Tx output power and temperature. Additionally, the sensor features ultra-low power operation enabled by the hardware's deep sleep mode. Its high level of integration makes this MMIC ideal for optimizing system costs.
