RFFM8550

4.9GHz to 5.85GHz 802.11a/n/ac WiFi

Switch + LNA Module

The RFFM8550 provides a complete integrated switch + LNA solution in

a single Front End Module (FEM) for WiFi 802.11a/n/ac systems. The

ultra-small form factor and integrated matching greatly reduces the

number of external components and layout area in the customer

applications. This simplifies the total front end solution by reducing the

bill of materials, system footprint, and manufacturing cost. The

RFFM8550 integrates a Single Pole Two Throw (SP2T)

Transmit/Receive (T/R) Switch and a 5.0GHz Low Noise Amplifier (LNA)

with bypass mode. The device is provided in a 1.5mm x 1.5mm x

0.40mm 8-pin DFN package.
