For additional with bypass, and a 5 GHz Power Amplifier (PA) intended for information, refer to Skyworks Denition of mobile/portable 802.11ac applications and systems. Lead (Pb)-Free, document number SQ04-0073. The LNA and PA disable functions ensure low leakage current in off mode. An integrated power detector is included to provide closed-loop power control within the system. The power detector also acts as a directional coupler to enhance detector accuracy over temperature and load mismatches. 16 15 14 13 1 GND 12 GND The device is provided in a compact, 16-pin 3 x 3 mm Quad Flat No-Lead (QFN) package.
