RF Amplifiers Procurement Notes

Verify component authenticity through authorized Skyworks channels due to End-of-Life status. Confirm package integrity and moisture sensitivity handling requirements prior to assembly. Cross-reference datasheet specifications against design requirements to ensure compatibility with existing RF circuitry.

RF Amplifiers Selection Notes

Select this component for designs requiring high efficiency in the 5 GHz UNII band. Evaluate thermal management capabilities given the 490 mA operating current. Ensure the QFN-20 footprint aligns with PCB layout constraints and that the system can accommodate the specified 5 V supply rail.

RF Amplifiers Part Context

This part belongs to Skyworks' portfolio of RF amplifiers targeting wireless infrastructure. It serves as a specialized solution for mid-band WLAN transmission, distinct from lower-frequency Wi-Fi or cellular PA families. The QFN-20 package facilitates compact integration into modern mobile and access point hardware.

RF Amplifiers Replacement Considerations

The component is listed as End-of-Life. No direct public substitute part numbers are confirmed in official documentation. Designers must evaluate alternative Skyworks PA families or third-party equivalents based on pinout and electrical parameter matching.
