5 GHz 802.11a/n/ac Wi-Fi Front End Module

    Qorvo's RFFM4591F provides a complete integrated solution in a single front end module (FEM) for WiFi 802.11a/n/ac systems. The small form 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 RFFM4591F 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 1.05mm, 16-pin laminate package. This module meets or exceeds the RF front end needs of IEEE 802.11a/n/ac WiFi RF systems.
