Functional Block Diagram
Product Description
The RFFM8800 provides a complete integrated solution in a single front end module (FEM)
for 802.11b/g/a/n WiFi dual band systems. The ultra-small form factor and integrated
matching minimizes the layout area in the customer's application and greatly reduces the
number of external components. This simplifies the total front end solution by reducing
the bill of materials, system footprint, and manufacturing cost. The RFFM8800 integrates a
power amplifier (PA), single pole triple throw switch (SP3T), LNA for 2.412GHz to 2.484GHz
and a power amplifier (PA), single pole double throw switch (SPDT), LNA for 4.9GHz to
5.85GHz. The device is provided in a 3.2mm x 5.2mm x 1.09mm, 30-pin laminate package.
This module meets or exceeds the RF front end needs of IEEE 802.11b/g/a/n WiFi
RF dual band systems.
