Description
The SKY85712-21 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.
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, 16-pin 3 x 3 mm Quad Flat
No-Lead (QFN) package. A functional block diagram is shown in
Figure 1. The pin configuration and package are shown in
Figure 2. Signal pin assignments and functional pin descriptions
are provided in Table 1.
