Strengthening the link between the real and the digital worldDEMO BGT60LTR11AIP Smallest completely autonomous 60GHz radar sensor MMIC for motion sensing
Infineon’s first completely autonomous 60GHz radar sensor MMIC for motion sensing
This demo features Infineon’s first completely autonomous radar sensor – the BGT60LTR11AIP. 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.
For evaluation of the BGT60LTR11AIP MMIC, this demo includes the BGT60LTR11AIP shield as well as 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 a demonstration software and a Radar GUI to display and analyze acquired data in time and frequency domain. It further enables to change various performance parameters of the BGT60LTR11AIP in order to evaluate this radar sensor.
