5 GHz WLAN Front-End Module (FEM): SKY85747-11


The SKY85747-11 is a 5 GHz WLAN Front-End Module (FEM) that is highly integrated and ideal for indoor and outdoor 802.11ax networking systems, and WLAN-enabled wireless video streaming systems.

The SKY85747-11 front-end module incorporates a 5 GHz single-pole, double-throw (SPDT) transmit/receive (T/R) switch, a 5 GHz low-noise amplifier with bypass, and a 5 GHz power amplifier. 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 dB of dynamic range.

Additional features include:

  • Integrated logarithmic power detector and directional coupler
  • Transmit gain: 34.5 dB typical
  • Supports 802.11ax output power: +18.5 dBm, -43 dB DEVM, MCS11
  • Small (24-pin, 3 x 5 mm) Land Grid Array (LGA) package
