Description
The SKY85724-11 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 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.
The device is provided in a compact, 10-pin 1.7  2.0 mm Dual
Flat No-Lead (DFN) package. A functional block diagram is shown
in Figure 1.
