RFFM4503

4.9GHz to 5.85GHz 802.11a/n/ac Wi-Fi

Front End Module

The RFFM4503 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 RFFM4503 integrates a 5GHz power amplifier (PA), single pole

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