The SKY85747-11 from Skyworks is a 5 GHz Front-End Module for 802.11ax networking and WLAN-enabled wireless video streaming systems. It incorporates a transmit/receive (T/R) switch, a high-gain low-noise amplifier (LNA) with bypass, and a power amplifier (PA). The FEM has a transmit gain of 34.5 dB, receive gain of 16 dB, and requires a supply voltage of 5.5 V. The LNA and PA disable functions ensure low leakage current in the off mode. An integrated logarithmic power detector is also included to provide closed-loop power control over 20 dB of dynamic range. This FEM is available in a 24-pin 3 x 5 mm Land Grid Array (LGA) package and is ideal for use in routers and gateways.
