RFFM4551

4.9GHz to 5.925GHz 802.11a/n/ac Wi-Fi

Front End Module

The RFFM4551 provides a complete integrated solution in a single

front end module (FEM) for Wi-Fi 802.11a/n/ac systems. The ultra-

small factor and integrated matching minimizes layout area in the

customer’s application and greatly reduces the number of external

components. Performance is focused on linear output power under a

number of conditions including duty cycle and packet length while

balancing power consumption needs of leading edge device

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

bill of materials, system footprint, and manufacturing cost.

The RFFM4551 integrates a 5GHz power amplifier (PA), single pole

two throw switch (SP2T) and an LNA with bypass. Also this FEM

includes integrated 2

band rejection filters. The device is provided in a 3.0mm x 3.0mm x

1.0mm, 16-pin laminate package. This module meets or exceeds the

RF front end needs of IEEE 802.11a/n/ac Wi-Fi RF systems.
