Qorvo's RFFM4558 provides a complete integrated solution in a single front end module (FEM) for Wi-Fi 802.11a/n/ac systems. The small form factor and integrated matching minimizes layout area in the application and greatly reduces the number of external components. Performance is focused on conserving power consumption while maintaining the highest linear output power and leading edge throughput. The RFFM4558 integrates a 5GHz power amplifier (PA), single-pole two-throw switch (SP2T) and a low noise amplifier (LNA) with bypass. Integrated filtering includes 2nd and 3rd harmonic as well as 2.4GHz rejection for dual-band dual-concurrent operation. The device is provided in a 2.5mm x 2.5mm x 0.98mm, 16-pin laminate package.
