5 GHz 1024 QAM WLAN Front-End Module

The SKY85772-11 is a highly integrated, 5 GHz front-end module (FEM) incorporating a 5 GHz 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 802.11ax applications and systems.

An integrated power detector is included to provide closed-loop power control within the system.

The device is provided in a compact, 16-pin 3 x 3 mm Quad Flat No-Lead (QFN) package.
