Front-end modules for Wi-Fi 6 applications
The SKY85334-11 and SKY85750-11 from Skyworks are 2.4 GHz and 5 GHz front-end modules (FEMs) respectively, the latest additions to the company’s portfolio of FEMs designed for growing retail, carrier and enterprise Wi-Fi 6 (802.11ax) applications.

These front-end modules for Wi-Fi 6 applications offer best-in-class linearity, power dissipation, and efficiency for access points, routers and gateways where regulatory, thermals or Power-over-Ethernet limitations demand low current consumption. Packaged in a compact, 16-pin 3- x 3-mm Land Grid Array (LGA), these highly integrated FEMs incorporate switching, low-noise amplifier (LNA) with bypass and power amplifier (PA).

Specifically, the SKY85334-11 is a 2.4 GHz FEM incorporating a 2.4 GHz single-pole, double-throw (SPDT) transmit/receive (T/R) switch, a 2.4 GHz LNA with bypass, and a 2.4 GHz PA with integrated digital pre-distortion (DPD) coupler intended for 802.11ax applications and systems.

The SKY85750-11 is a 5 GHz FEM incorporating a 5 GHz single-pole, double-throw (SPDT) transmit/receive (T/R) switch, a 5 GHz LNA with bypass, and a 5 GHz PA with integrated digital pre-distortion (DPD) coupler intended for 802.11ax applications and systems.

The LNA and PA disable functions ensure low leakage current in off mode. An integrated logarithmic power detector is included to provide closed-loop power control within the system.

Both devices offer very high linearity to support 1024 QAM with MU-MIMO applications and simultaneously maximize capacity and throughput. Low power consumption makes the FEMs ideal for PoE applications in high density deployments.

The front-end modules are FCC Compliant for harmonics to reduce post FEM losses and improve overall performance, while high receive sensitivity improves Rx throughput, ideal for mesh applications where bidirectional speed and capacity are critical
