Description
The SKY85806-11 is a complete 802.11a/b/g/n/ac Wireless
Local Area Network (WLAN), RF front-end module (FEM) that
provides all the functionality of a power amplifier (PA), filtering,
power detector, transmit/receive (T/R) switch, diplexer, and
associated matching. The SKY85806-11 provides a complete
2.4 GHz and 5 GHz WLAN RF solution, from the output of the
transceiver to the antenna in an ultra-compact form factor.
Designed to meet the stringent linearity conditions of the
802.11ac standard, the SKY85806-11 delivers less than 2%
error vector magnitude (EVM) at the rated Alternating Current
(AC) power.
Designed for ease of use, all RF ports are matched to 50
Ω
to
simplify the layout of the printed circuit board (PCB) and the
interface to the transceiver. The SKY85806-11 also includes a
transmitter power detector with +20 dB of dynamic range for
each transmit chain. Each power amplifier has a separate
digital enable control for transmitter on/off control. The power
ramp rise/fall time is less than 0.5 μs.
The SKY85806-11 provides Local Oscillator (LO) filters for the
2 GHz and 5 GHz transmit paths. The SKY85806-11 is packaged
in a small 4.0 x 3.0 x 0.8 mm, Quad Flat No-Lead (QFN)
package.
A block diagram of the SKY85806-11 is shown in Figure 1. The
device package and pinout are shown in Figure 2. Signal pin
assignments and functional pin descriptions are described in
Table 1.

Note 1:
Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION:
Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
