SKY85331-11
2.4 GHz High-Power 802.11ax WLAN Front-End Module
The SKY85331-11 is a highly integrated, 2.4 GHz front-end
module (FEM) incorporating a 2.4 GHz single-pole, double-throw
(SPDT) transmit/receive (T/R) switch, a 2.4 GHz low-noise
amplifier (LNA) with bypass, and a 2.4 GHz power amplifier (PA)
intended for high-power 802.11ax applications and systems.
The LNA and PA disable functions ensure low leakage current in
the off mode. An integrated logarithmic power detector is
included to provide closed-loop power control over 20 dB of
dynamic range.
The device is provided in a compact 24-pin 3 x 5 mm conformally
shielded Land Grid Array (LGA) package, which may reduce the
front-end board space by more than 50 percent.
