WiFi 6 FEM Features Log Power Detector

RFMW announces design and sales support for an 802.11ax (WiFi 6) front-end module (FEM) from Skyworks Solutions. The SKY85748-11 offers high level integration with a 5 GHz SPDT transmit/receive (T/R) switch, a 5 GHz LNA with bypass, and a 5 GHz power amplifier offering 24.5 dBm peak output power @ MCS0. Intended for Enterprise applications, power dissipation at 21 dBm is only 1.15 Watts using a 3.3V supply, ideal for Power-over-Ethernet (POE) designs. The integrated logarithmic power detector provides closed-loop power control with sensitivity down to 5 dBm. Transmit gain is 32 dB while receive gain is 13 dB on this fully matched I/O FEM. The SKY85748-11 requires minimal PCB space with a 2.5 x 2.5 mm QFN package.
