RF Amplifiers Procurement Notes

Verify component status as the RFX240 is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing design-in requirements before sourcing. Check for valid RoHS compliance documentation if required for specific regulatory environments. Validate that the 16-QFN package matches the target PCB footprint.

RF Amplifiers Selection Notes

Select this component for designs requiring high linearity and power output in the 2.4 GHz band. Consider the 5 V supply requirement and 210 mA current draw for power budget calculations. The 30 dB gain and 32 dBm P1dB make it suitable for applications needing robust signal transmission. Evaluate thermal management needs due to the exposed pad package design.
