The ATF65254-11 is a highly efficient, highly integrated, 2.4GHz front-end module (FEM) incorporating a 2.4 GHz single-pole, double-throw
(SPDT) transmit/receive (T/R) switch, a 2.4GHz low-
noise amplifier (LNA) with bypass, and a 2.4 GHzpower amplifier (PA) with integrated digital pre-distortion (DPD) coupler intended for 802.11ax applications and systems.
The LNA and PA disable functions ensure low leakage current in off mode. 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 3 x 3 mm
bypass, and T/R switch
