SKY85347-11 WLAN Front-End Module Skyworks Solutions Inc. SKY85347-11 WLAN Front-End Module is a complete 802.11ax WLAN device. The SKY85347-11 acts as a fully matched power amplifier (PA), power detector, low-noise amplifier (LNA), and single-pole, double-throw (SPDT) switch. The SKY85347-11 is a 2.4GHz WLAN RF solution from the transceiver output to the antenna and the transceiver input. The LNA increases receive sensitivity for embedded solutions. This improves range and overcomes insertion loss of cellular filters for mobile applications.
