RFFM8850P
RFFM8850P
Dualband 2.4GHz and 5.0GHz 802.11b/g/n/a/ac
Wi-Fi® Switch + LNA Front End Module
Package: QFN, 16-pin,
2.3mm x 2.3mm x 0.33mm
The RFFM8850P provides a complete dualband integrated Switch +
LNA solution in a single Front End Module (FEM) for Wi-Fi®
802.11b/g/n/a/ac and Bluetooth® systems. The ultra-small form factor
and integrated matching greatly reduces the number of external
components and layout area. The RFFM8850P integrates a 2.4GHz
SP3T Transmit/Receive Switch, a 5.0GHz SP2T Transmit/Receive
Switch, a 2.4GHz Low Noise Amplifier with bypass mode, and a 5.0GHz
Low Noise Amplifier with bypass mode.

PCB Patterns
Note:
Thermal vias for center slug “C” should be incorporated into the PCB design. The number and size of thermal vias will depend on the application,
power, dissipation and electrical requirements. Example of the number and size of vias can be found on the RFMD evaluation board layout (gerber
files are available upon request)
