功能特点
RDA5990 integrates industry-lead WLAN, Bluetooth and FM radio tuner into one chip and is optimized for mobile applications. WLAN, Bluetooth and FM can work simultaneously and independently, with low power consumption levels target to battery powered devices. For the highest integration level, the required board space has been minimized and customer cost has been reduced. Manufacturers can easily and fast integrate RDA5990 on their product to enable a rapid time to market.
RDA5990 uses CMOS process with a compact 6*6mm 48-pin QFN package.
