The Infineon communication & wireless development tools is a fully integrated microwave motion sensor including antennas as well as a built-in motion and direction of motion detector and a state machine allowing fully autonomous operation of the MMIC without any external microcontroller. An integrated frequency divider with a Phase-Locked Loop (PLL) provides VCO frequency stabilization.

Up to 7 m detection range for human targets
Less than 2 mW power consumption possible
Requires minimal external circuitry
