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..
