RFFM4501

3.0V TO 5.0V, 4.9GHz TO 5.85GHz

802.11a/n/ac FRONT END MODULE

The RFFM4501 provides a complete integrated solution in a single front

end module (FEM) for WiFi 802.11a/n/ac systems. The ultra-small form

factor and integrated matching minimizes the layout area in the cus-

tomer's application and greatly reduces the number of external compo-

nents. This simplifies the total front end solution by reducing the bill

of materials, system footprint, and manufacturability cost. The RFFM4501

integrates a power amplifier (PA), single pole double throw switch (SPDT),

LNA with bypass, and a power detector coupler for improved accuracy.

The device is provided in a 3mm x 3mm x 1.05mm, 16-pin laminate pack-

age. This module meets or exceeds the RF front end needs of IEEE

802.11a/n/ac WiFi RF systems.
