描述 Description

The SKY85747-11 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 high-gain low-noiseamplifier (LNA) with bypass, and a 5 GHz power amplifier (PA)intended for high-power 802.11ax applications and systems.

The LNA and PA disable functions ensure low leakage current inthe off mode. An integrated logarithmic power detector isincluded to provide closed-loop power control over 25 dB ofdynamic range.

The device is provided in a compact, 24-pin 3 x 5 mm Land GridArray (LGA) package, which may reduce the front-end boardspace by more than 50 percent.
