RFFM4503
RFFM4503
4.9GHz to 5.85GHz 802.11a/n/ac Wi-Fi
Front End Module
Package: Laminate, 16-pin,
3.0mm x 3.0mm x 1.0mm
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.
