SKY85703-11

5 GHz WLAN Front-end Module


The SKY85703-11 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 802.11ac applications and systems.

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.

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