RF Amplifiers Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, with distributors indicating non-sale status in certain regions. Verification of current stock levels and alternative sourcing channels is essential before integration into new designs due to discontinuation status.

RF Amplifiers Selection Notes

Engineers should evaluate the silicon technology constraints against GaAs alternatives if higher frequency or lower noise performance is required. The 750 mA current draw necessitates adequate power management and thermal considerations. Verify that the 3.9 GHz upper frequency limit aligns with specific system requirements, as this model targets the 3.5 GHz band specifically.
