3.2 Hardware Architecture
The module design based on the MARVELL 88W8787 single chip integrated WiFi and BT
MAC/Baseband/RF Which implements IEEE802.11b/g/n and BTv.30+HS
Figure 1 Functional Block Diagram
MARVELL 88W8787 is a highly integrated, low-cost, low-power IEEE802.11 b/g /n MAC
/Baseband / RF WLAN and Bluetooth Baseband/RF. The SIP 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 88W8787 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.
To maximize performance between WLAN and Bluetooth, three antennas will be required.
Two antennas are dedicated to the WLAN interface to provide diversity. The third antenna
will be dedicated for Bluetooth.
