The BGT60LTR11AIP MMIC is a fully integrated microwave motion sensor including Antennas in Package (AIP) as well as built-in motion and direction of motion detectors. A state machine enables operation of the device autonomously, i.e., without an external microcontroller or further signal processing. The MMIC has four quad-state input pins that give the performance parameters flexibility, even in this autonomous mode. The detection threshold or sensitivity has 16 different levels in order to fulfill a configurable detection range from 0.5 m up to 7 m with a typical human target Radar Cross Section (RCS). Hold time is also configurable in 16 levels in autonomous mode, which allows detection status to be held from 0.1 s up to 30 minutes.  The device can achieve power consumption of less than 2mW with adjustable duty cycling.  

The small, 3.3 × 6.7 × 0.56-mm³ MMIC has integrated antennas. This eliminates antenna design complexity at user end and allows the PCBs to be designed with standard FR4 materials.

These features make this small-sized radar solution a compelling smart and cost-effective replacement for conventional PIR sensors, even in low power or battery-powered products. In addition, the BGT60LTR11AIP addresses a huge variety of applications that can benefit from smart motion detection - whether to save energy, protect privacy or improve the user experience of smart devices.
