SKY85702-11
5 GHz WLAN Front-end Module

The SKY85702-11 is a highly-integrated, 5 GHz Front-End Module (FEM) incorporating a 5 GHz Single-Pole, Double-Throw (SPDT) transmit/receive (T/R) switch, and a 5 GHz Power Amplifier (PA) intended for mobile/portable 802.11n/ac applications and systems. The device operates from a single supply voltage of 3.6 V.

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

Features
