Radar sensor is smallest 60GHz with antennas in package, says Infineon
The BGT60UTR11AIP Xensiv 60GHz radar sensor is in a compact antenna in package (AIP) for a footprint of just 16mm2, for use in consumer electronics, IoT applications and healthcare devices, said Infineon Technologies.
The company said it is the smallest 60GHz radar sensor with AIP available today and is suitable for small devices, for example 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. 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. It has a wide bandwidth of 5.6GHz and a ramp speed of 400MHz per microsecond to enable high resolution frequency modulated continuous wave (FMCW) operation with sensitive presence and motion detection at up to 15m (50 feet). The sensor also enables precise distance measurement, 1D gesture and vital sign detection, all with sub-mm motion detection capabilities.
The integrated antennas provide a ±60 degree field of view while an integrated state machine enables real time data acquisition without processor interaction. The MMIC also includes a 12-bit ADC with a sampling rate of up to 4Msamples per second).
The MMIC’s built-in broadcast mode allows multiple chips to be synchronised. It also includes on-chip sensors for measuring Tx output power and temperature. A deep sleep mode ensures the sensor’s low power operation, added Infineon.
The Xensiv 60GHz radar BGT60UTR11AIP sensor can be ordered now and will begin shipping in Q4 2023. The Demo BGT60UTR11AIP and the radar development kit (RDK) are both available for download from the Infineon Developer Center (IDC).
