Description
The SKY85312-11 is a complete 802.11b/g/n/ac WLAN RF front-
end module (FEM) with a Bluetooth^® port. The device provides all
the functionality of a fully matched power amplifier (PA), power
detector, harmonic filter, low-noise amplifier (LNA), single-pole,
double-throw (SPDT) switches, and a single-pole, triple-throw
(SP3T) switch.
The SKY85312-11 provides a complete 2.4 GHz WLAN RF solution
from the output of the transceiver to the antenna, and from the
antenna to the input of the transceiver. The LNA increases the
receive sensitivity of embedded solutions to improve range or to
overcome the insertion loss of cellular filters (often included for
mobile applications).
The SKY85312-11 also includes a transmitter power detector with
20 dB of dynamic range, and a digital enable control for
transmitter power ramp on/off control.
The device is provided in a compact, 16-pin 2.3 x 2.3 mm Quad
Flat No-Lead (QFN) package. A functional block diagram is shown
in Figure 1.
