SKY85738-11

5 GHz WLAN Front-End Module

Please note: SKY85738-11 is being discontinued and is not recommended for new designs. The suggested replacement is SKY85747-11

The SKY85738-11 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-noise amplifier (LNA) with bypass, and a 5 GHz power amplifier (PA) intended for high-power 802.11ac applications and systems.

The LNA and PA disable functions ensure low leakage current in the off mode. An integrated power detector is included to provide closed-loop power control within the system.

The device is provided in a compact, 24-pin 3 x 5 mm laminate package, which may reduce the front-end board space by more than 50 percent.
