The ATF65684-11 is a highly integrated, front- end module (FEM) incorporating a single-pole, double-throw (SPDT) transmit/receive (T/R) switch, a high-gain low-noise amplifier (LNA) with bypass, and a 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 package, which may reduce the front- end board space by more than 50 percent.
