The CHW1010 from CoreHW is RF Switch that is designed for indoor positioning and direction-finding applications. It consists of 16 single-ended antenna ports and enables very high direction-finding accuracy needed especially for Bluetooth 5.1 Angle of Arrival (AoA) and Angle of Departure (AoD) indoor positioning feature. The CHW1010 has a low phase-mismatch between switch paths which minimizes residual error in computed angles of beam direction and subsequently improves estimated location accuracy. It has a soft antenna switching function (AoDTX-mode) that enables high-performance AoD operation, reduces unwanted spectral emissions, and helps in compliance with Bluetooth 5.1 standards.
The CHW1010 switch has an insertion loss of 2.7 dB and a start-up time of 15 μs. It is ideal for use in accurate indoor positioning and navigation systems, asset tracking in factories, offices, logistics, etc., item finding, access control, people tracking, wayfinding, point-of-interest services, proximity marketing, shopping guidance & assistance, equipment & facilities utilization, and consumer behavior analysis applications.
