5 GHz 802.11ax Ultra-Linear WLAN Front-End Module With Integrated Log Detector: SKY85748-11

Source: Skyworks Solutions, Inc.

The SKY85748-11 is a 5 GHz WLAN Front-End Module (FEM) with an integrated log detector that is ideal for 802.11ax networking and personal computing systems, PC cards, PCMCIA cards, mini-cards, half mini-cards, and WLAN-enabled wireless video systems.

The SKY85748-11 front-end module incorporates a 5 GHz single-pole, double-throw (SPDT) transmit/receive (T/R) switch, a 5 GHz low-noise amplifier (LNA) with bypass, and a 5 GHz power amplifier (PA). An integrated logarithmic power detector is included to provide closed-loop power control.

Additional features include:

  • Integrated logarithmic power detector and directional coupler
  • Transmit gain: 32 dB typical
  • Receive gain: 13 dB
  • Small (16-pin, 2.5 x 2.5 mm) QFN package
