For additional information, refer to Skyworks Definition of Green TM, document number SQ04- 0074. Figure 1. SKY85747-11 Block Diagram Description The SKY85747-11 is a highly integrated, 5 GHz front-end module (FEM) incorporating a 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 d B of dynamic range. The device is provided in a pact, 24-pin 3 x 5 mm Land Grid Array (LGA) package, which may reduce the front-end board space by more than 50 percent. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1. Figure 2.
