ATF65555-11
5 GHz WLAN Front-End Module
The ATF65555-11 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 applications and systems.
An integrated power detector is included to provide closed-loop power control within the system.
The device is packaged in a compact 16-pin 3 x 3 mm Quad Flat No-Lead (QFN).
