Figure 1 Functional Block Diagram
MARVELL 88W8688BFL is a highly integrated, low-cost, low-power IEEE802.11 b/g MAC
/Baseband / RF WLAN and Bluetooth Baseband/RF. The mini Module apply to WLAN /Bluetooth
cellular handsets ,WLAN/Bluetooth headsets, portable audio/video devices and accessories ,
gaming platforms, and WLAN/Bluetooth enabled digital still cameras and printers.
The single chip MARVELL 88W8688BFL interfaces directly with both the RF and digital signals.
It transmits and receivers RF signals at 2.4GHz to and from the antenna and digital signals to and
from the host interface. A power management (PMU) is placed in the off Board to provide power
for all components in the module and also can save precious board space.
