RF Amplifiers Procurement Notes

Verify availability carefully as the RMPA2453 is classified as obsolete or discontinued by the manufacturer. Sourcing may require checking secondary distributors or existing stock from previous production runs. Confirm the specific revision and packaging type if replacing active inventory. Ensure compatibility with existing PCB layouts due to the fixed 16-LCC footprint.

RF Amplifiers Selection Notes

Select this component only for designs requiring a 2.4-2.5 GHz RF power amplifier in a compact 16-LCC package. Consider the obsolete status when planning long-term production. Evaluate alternative modern RF PA solutions if new design-in is required. Verify thermal management requirements for the exposed pad configuration during integration.

RF Amplifiers Part Context

This part belongs to onsemi's portfolio of wireless and RF integrated circuits. It is categorized under RF amplifiers specifically tailored for consumer wireless communication standards. The component represents legacy silicon-based RF power amplification technology used in earlier generations of WiFi hardware.

RF Amplifiers Replacement Considerations

As the RMPA2453 is obsolete, direct substitutes are not explicitly confirmed in public documentation. Engineers should evaluate newer onsemi RF PA models or competitors offering compatible 2.4 GHz performance in similar packages. Pin-to-pin replacements must be verified against official datasheets.
