RF Front End (LNA + PA) Procurement Notes

Verify component authenticity through authorized Skyworks distributors or direct manufacturer channels. Confirm the specific -11 suffix matches project requirements, as it denotes the specific tape-and-reel packaging variant. Request official datasheets and RoHS compliance documentation to ensure adherence to environmental regulations. Validate that the 24-LGA package dimensions align with PCB layout constraints before finalizing procurement orders.

RF Front End (LNA + PA) Selection Notes

Select this component when a highly integrated dual-band FEM is required for space-constrained WLAN designs. The SKY85803-11 offers a simplified bill of materials by combining active components into a single package. Ensure the application supports the 3.3V operating voltage and accommodates the thermal requirements of the exposed pad LGA footprint. Compare against standalone amplifier solutions if higher individual gain stages are necessary.
