QPF8538 Wi-Fi Front End Module 4900MHz to 5925MHz Product Description The QPF8538 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 a balance of efficiency to linear power that increases the range and throughput of connections. Control lines are reduced to a two-line control scheme Package: Laminate, 16-pin, 2.3mm x 2.3mm x 0.63mm max The QPF8538 integrates a 5GHz power amplifier (PA), single-pole two-throw switch (SP2T) and a low noise amplifier (LNA) with Feature Overview nd rd bypass. Integrated filtering includes 2 and 3 harmonic as well as 2.4GHz rejection for dual-band dual-concurrent operation. A DC P = +17dBm, 802.11ac, VHT80 MCS9 at-35dB Dynamic OUT power detector is integrated for application calibration enablement. EVM The device is provided in a 2.3mm x 2.3mm x 0.0.63mm, 16-pin POUT = +18dBm, 802.11n, HT20/40 MCS7 at-30dB Dynamic laminate package.
