1BDescription

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. The pin configuration and package are shown

in Figure 2. Signal pin assignments and functional pin

descriptions are provided in Table 1.
