Advantages

U231 product provides the highest level of integration and most aggressive BOM cost by integrating IEEE 802.11b/g and Bluetooth V2.0+EDR into a single MAC/Baseband chip utilizing a single 2.4GHz transceiver. Integrated on-chip power amplifier and LNA reduce external component count, while still able to deliver ample transmit power for most applications. The highly optimized software radio DSP technology enables U231 to integrate class 1 Bluetooth V2.0+EDR function without any added cost to the total solution. No extra antenna, PA, RF transceiver, resistor, capacitor, crystal or any components are needed. The software solution even guarantees the Bluetooth RF performance if the wireless LAN performance is tested to be good. It eliminates the need for system manufacturers to separately test the module's Bluetooth RF performance, therefore reduce the testing time and cost.
