The SKY85791-11 is a highly integrated front-end
module (FEM) incorporating a transmit/receive (T/R)
switch, a low-noise amplifier (LNA) with bypass,
and a power amplifier (PA) for Wi-Fi 7 (802.11be)
applications and systems.
The PA output includes a coupler to allow for digital
pre-distortion (DPD) in applications. In DPD
applications, the coupler is also used in place of the
power detector.
An integrated logarithmic power detector is
included to provide closed-loop power control within
the system. The device is provided in a compact 16-pin
QFN package.
