RF Switches Optimized for Indoor Positioning Systems

CoreHW CHW10X0: AoA and AoD Switch

CHW10X0 is a chip product family supporting Bluetooth® Low Energy applications. CHW1010 and CHW1020 are the new generation RF Switches designed to transfer the real-time location data with a powerful indoor positioning and outstanding power efficiency.

CHW10X0 enables very high direction-finding accuracy needed especially for Bluetooth 5.1 Angle of Arrival (AoA) and Angle of Departure (AoD) indoor positioning feature. CHW10X0 switches bring the pinpoint accuracy of GPS to indoors. Using several beacons, CHW10X0 enable direction finding also in 3D.

CHW10X0 key benefits include a small footprint with a clever design, making several previously needed components redundant.
