SKY85716-11 A Nominal Power FEM Aids 5GHz Routers


FEM from Skyworks Solutions availabe in 2.3 x 2.3 mm QFN package can be used in access points, routers and gateways where minimal board space is available



The SKY85716-11 is a highly integrated, 5 GHz front-end module (FEM) incorporating a 5 GHz single-pole, double-throw (SPDT) transmit/receive (T/R) switch, a 5 GHz low-noise amplifier (LNA) with bypass, and a 5 GHz power amplifier (PA) intended for mobile/portable 802.11n/ac applications and systems.

An enable/disable function is included that allows power savings during off mode. An integrated logarithmic power detector with 20 dB of dynamic range is included to provide closed-loop power control within the system when operating in either high power mode or power save mode.

The device is provided in a compact, 16-pin, 2.3 x 2.3 x 0.33 mm Quad Flat No-Lead (QFN) package


  • Fully matched, with integrated 5 GHz PA with harmonic, LNA with bypass mode and SPDT switch
