RFFM8550
4.9GHz to 5.85GHz 802.11a/n/ac WiFi
Switch + LNA Module
Package: DFN, 8-pin,
1.5mm x 1.5mm x 0.40mm
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)

RF bidirectional antenna port matched to 50Ω. An external DC block is required.
Receive switch control pin. See switch truth table for proper voltage level.
Control voltage for the TX switch. See truth table for proper voltage level.
Supply voltage for the LNA. See applications schematic for bypassing components.
Control voltage for the LNA. When this pin is set to a LOW logic state, the bypass mode is enabled.
RF output port for the 802.11a/n/ac LNA. This port is matched to 50Ω and DC blocked internally
This pin is not connected internally and can be left floating or connected to ground.
RF input port for the TX throw of the T/R switch. An external DC block is required
N/C
TX
Ground connection. The backside of the package should be connected to the ground plane through a short
path, i.e., PCB vias under the device are recommended.
