RFFM8505
4.9GHz to 5.85GHz 802.11a/n/ac WiFi
Front End Module
The RFFM8505 provides a complete integrated solution in a single front
end module (FEM) for WiFi 802.11a/n/ac systems. The ultra-small
factor and integrated matching minimizes 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 RFFM8505
integrates a 5 GHz power amplifier (PA), single pole double throw switch
(SP2T), LNA with bypass, and a power detector coupler for improved
accuracy. The device is provided in a 2.5mm x 2.5mm x 0.40mm, 16-
pin QFN package. This module meets or exceeds the RF front end
needs of IEEE 802.11a/n/ac WiFi RF systems.
