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.
