SKY85331-11
2 GHz WLAN Front-End Module

The SKY85331-11 is a highly integrated, 2 GHz front-end module (FEM) incorporating a 2 GHz single-pole, double-throw (SPDT) transmit/receive (T/R) switch, a 2 GHz low-noise amplifier (LNA) with bypass, and a 2 GHz power amplifier (PA) intended for high-power 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 device is provided in a compact 24-pin 3 x 5 mm Land Grid Array (LGA) package.
