CoreHW CHW10X0 AoA/AoD Switch

CoreHW CHW10X0 AoA/AoD Switch

CoreHW RF Switch Optimized for Indoor Positioning

CoreHW CHW10X0 is a chip product family supporting Bluetooth® Low Energy applications. 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.

CoreHW CHW10X0 brings the pinpoint accuracy of GPS indoors. Using several beacons, CHW10X0 enables direction finding also in 3D. Its key benefits include a small footprint with a clever design, making several previously needed components redundant.


  • Asset tracking
  • Access control and security services
  • Proximity advertising
  • Point of interest services
  • Accurate positioning and navigation systems
  • Aftermarket automotive applications


  • Very high location accuracy in real life conditions
  • Low device, system and installation cost
  • Very low energy consumption
  • Easy development of client applications – will be supported by all coming mobile devices
  • Suitable also for outdoor proximity positioning

Bluetooth 5.1 AoA/AoD Enabled by CoreHW RF Switch

A new direction-finding feature in Bluetooth 5.1 makes it possible for Bluetooth devices to determine the direction of a Bluetooth signal transmission with a high degree of accuracy using AoA/AoD methods.

CHW10X0 supports Bluetooth 5.1 AoA/AoD positioning application. It features 16 phase-matched antenna ports which can be used to drive single-ended or differential antennas. Absorptive and reflective antenna terminations are also available.

CoreHW offers custom antenna design service for various beacon enclosure shapes and sizes.
