SKY85330-11 WLAN Front-End Module Skyworks Solutions Inc. SKY85330-11 WLAN Front-End Module is a complete 802.11b/g/n 256 QAM device. The SKY85330-11 acts as a fully matched power amplifier (PA), power detector, low-noise amplifier (LNA), and single-pole, double-throw (SPDT) switch. The SKY85330-11 provides a complete 2.4GHz WLAN RF solution from the output of the transceiver to the antenna, and from the antenna to the input of the transceiver. The LNA increases the receive sensitivity of embedded solutions to improve range or to overcome the insertion loss of cellular filters (often included for mobile applications).
