RF Amplifiers Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Skyworks Solutions or authorized distributors before procurement. Confirm that the ordering suffix matches the required package type and tape/reel specifications. Ensure compatibility with your design's thermal management requirements and supply voltage constraints. Cross-reference part numbers to avoid obsolete variants.

RF Amplifiers Selection Notes

Select this component when designing for cellular bands between 1.5 GHz and 3.8 GHz requiring high linearity and low noise. Compare its 20 dB gain and 0.8 dB noise figure against alternatives if stricter sensitivity or power efficiency is needed. Consider the 5 V supply requirement and ensure the PCB layout supports the SMD package footprint for optimal RF performance.
