Typical Applications
Where this part most commonly drives sourcing urgency.
Wi-Fi 6 Access Points
Integrated FEM reduces BOM count in tri-band 802.11ax access point designs.
CPE and Home Gateways
Used in residential gateway platforms requiring 5 GHz band coverage with high output power.
Industrial Wi-Fi Modules
Deployed in factory automation wireless nodes where RF performance and reliability are critical.
Why This Part Gets Requested
Why procurement teams come to us for SKY85743-21 — and why standard channels often fall short.
Wi-Fi 6 Ramp
Mass deployment of Wi-Fi 6 infrastructure created simultaneous demand spikes across all 5 GHz FEM suppliers.
Skyworks Allocation
Skyworks manages FEM supply through tiered allocation — spot availability is limited during peak demand periods.
Typical Shortage Scenarios
Common situations where teams contact us under time pressure.
Production Line Delays
Wi-Fi 6 router manufacturers report 16–26 week lead times on 5 GHz FEMs during peak ramp.
Single-Source Risk
Many reference designs are locked to SKY85743-21 — substitution requires RF re-certification.
