Infineon has developed the first completely autonomous 60 GHz radar sensor MMIC for motion sensing applications. The 60 GHz radar MMIC is a fully integrated microwave motion sensor including Antennas in Package (AIP) as well as integrated detectors for motion and direction of motion. A state machine enables operation of the device without any external microcontroller. In this autonomous mode, it detects a human target up to 5 m with a low power consumption of less than 5 mW. These features make the small sized radar solution a compelling smart and cost-effective replacement for conventional PIR sensors in low power or battery-powered applications.
To evaluate this sensor Infineon has developed a demo that consists of the BGT60LTR11AIP radar sensor MMIC and the Infineon Radar Baseboard MCU7.
The BGT60LTR11AIP shield can be attached to an Arduino MKR board or the included Infineon Radar Baseboard MCU7. Infineon’s Toolbox supports this platform with demonstration software and a Radar GUI to display and analyze acquired data in the time and frequency domain. It further enables to change of various performance parameters of the BGT60LTR11AIP to evaluate this radar sensor.
Key features of BGT60LTR11AIP MMIC:
- 3.3 x 6.7 x 0.56 mm package size.
- 1Tx 1Rx Antennas in Package (AIP) with 80 ° field of view.
- Integrated detectors for motion and direction of motion.
- Multiple modes of operation including a completely autonomous mode.
- Adjustable performance parameters such as detection sensitivity, hold time, and frequency of operation.
For evaluation of the BGT60LTR11AIP MMIC, this demo includes the BGT60LTR11AIP shield as well as the Infineon Radar Baseboard MCU7.
