Description
The SKY85717-21 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, 16-pin 2.5 x 2.5 x 0.4 mm
Quad Flat No-Lead (QFN) package. A functional block diagram is
shown in Figure 1.
