Description
The SKY85310-21 is a complete 802.11b/g/n 256 QAM 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, low-noise amplifier (LNA), and
single-pole, triple-throw (SP3T) switch.
The SKY85310-21 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 SKY85310-21 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 an ultra-compact, 16-pin 3 x 3 mm
Quad Flat No-Lead (QFN) package. A functional block diagram is
shown in Figure 1..
