RDA5991 DATASHEET

1. General Description

RDA5991 integrates 802.11b/g/n MAC, PHY, 2.4Ghz radio, PowerAmplifier and antenna switch 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 RDA5991 on their product to enable a rapid time to market.

RDA5991 uses a compact 4*4 BGA package.
