5 GHz WLAN Front-end Module

The SKY85710-11 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 high power 802.11ac applications and systems.

The LNA and PA disable functions ensure low leakage current in the off mode. An integrated power detector is included to provide closed-loop power control within the system.

The device is provided in a compact, 24-pin 3 x 5 mm Quad Flat No-Lead (QFN) package.
