ATF65546-11
2.4 GHz 802.11ax Ultra-Linear WLAN Front-End Module with Integrated Log Detector
The ATF65546-11 is a highly integrated, 5 GHz front-end module (FEM) incorporating a 5 GHz single-pole, double-throw (SPDT) transmit/receive (T/R) switch, a 5 GHz low- noise amplifier (LNA) with bypass, and a 5 GHz power amplifier (PA) intended for mobile/portable 802.11ax 1024 QAM 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-pin2.5 x 2.5 mm Quad Flat No-Lead (QFN) package.
