SKY85734-11

5 GHz, 802.11ac Front-End Module

The SKY85734-11 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.

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

The device is provided in a compact, 12-pin 2.0 x 2.0 x 0.6 mm Multi-Chip Module (MCM) package.
