Description
The SKY85720-11 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 802.11n/ac applications and systems.
An enable/disable function is included that allows power savings
during off mode. An integrated logarithmic power detector with
20 dB of dynamic range is included to provide closed-loop power
control within the system when operating in either high power
mode or power save mode.
The device is provided in a compact, 16-pin, 2.3  2.3 
0.33 mm Quad Flat No-Lead (QFN) package. A functional block
diagram is shown in Figure 1.
