RF Micro Devices has announced that Air2U is using its SiW3000 UltimateBlue single-chip Bluetooth component in its USB adapter.
The adapter has been certified by Microsoft as an authorised device for testing the compatibility of Bluetooth wireless products operating with the Windows XP system. The Air2U USB adapter is available in a WHQL qualification development kit from the RFMD eStore at http://www.rfmd.com/order.asp. The WHQL certification ensures compatibility and interoperability with Microsoft products.
The SiW3000 is a single-chip Bluetooth solution that combines a direct conversion radio modem with an ARM7TDMI processor core, Bluetooth baseband logic and complete protocol software in read only memory (ROM). All active RF components have been integrated into the CMOS-based IC, making it a complete low-cost solution. The SiW3000's baseband delivers the extra millions of instructions per second required to integrate additional software and enables full scatternet support without performance degradation. The SiW3000 is Bluetooth Specification Version 1.2 qualified and supports adaptive frequency hopping (AFH). It also integrates RFMD's UltimateBlue Coexistence technology to address the interference issues when Bluetooth and 802.11 wireless technologies are collocated in the same device (such as a notebook PC). This allows users to operate Bluetooth and other 2.4GHz wireless technologies simultaneously while maintaining optimal system throughput, range and responsiveness.
