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 2nd and 3rd Harmonic filters and integrated out of
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.
