RFFM4555
Wi-Fi Integrated Front End Module
4.9GHz to 5.925GHz
The RFFM4555 is a front end module (FEM) designed for 802.11a/n/ac
applications. The integrated single-pole double throw switch and low
noise amplifier with bypass greatly reduces the layout area, bill of
materials and manufacturability cost in the customer application. The
RFFM4555 is optimized to pair with Wi-Fi power amplifiers such as the
RFPA5512/RFPA5522/RFPA5542 to create a complete Tx and Rx
solution. The device is provided in a 1.5mm x 1.5mm x 0.455mm DFN
package that meets or exceeds the power requirements of
IEEE802.11a/n/ac Wi-Fi RF systems
.

RFMD Green: RoHS status based on EU
Directive 2011/65/EU (at time of this
document revision), halogen free per IEC
61249-2-21, < 1000ppm each of
antimony trioxide in polymeric materials
and red phosphorus as a flame retardant,
and <2% antimony in solder.
Exceeding any one or a combination of the Absolute
Maximum Rating conditions may cause permanent
damage to the device. Extended application of Absolute
Maximum Rating conditions to the device may reduce
device reliability. Specified typical performance or
