The DW3210 from Qorvo is an Ultra-Wideband (UWB) Transceiver IC that operates in the UWB Channels 5 (6.5 GHz) and 9 (8 GHz). This UWB IC is interoperable with the Apple U1 chip. It delivers a data rate of up to 6.8 Mbps and has a ranging accuracy of 10 cm. The transceiver is based on IEEE802.15 4a and 4z-BPRF standards and supports FiRa compliant functions like two way ranging, time difference of arrival and phase difference of arrival. It has two antenna ports that allows Phase Difference of Arrival implementation with a single chip. The UWB IC can securely measure time of flight and payload encryption and has low power consumption features. It requires a DC supply of 2.4-3.6 V and is suitable for coin cell applications.
The DW3210 is available in a QFN package that measures 5 x 5 mm and can be controlled via an SPI interface. It is ideal for mobile phones, high precision real time location systems, location-aware wireless sensor networks, asset tracking, factory/warehouse automation & security, healthcare staff & patient location, retail security, navigation, customer analytics and connected home applications.
