RF Detectors Procurement Notes

This component is classified as End-of-Life (EOL) and will be discontinued by the manufacturer. Verification of final availability through official channels is essential before procurement planning. Designers should review the discontinuation notification dated May 21, 2025, to assess impact on production schedules. Alternative sourcing strategies must be evaluated immediately due to the confirmed obsolescence status.

RF Detectors Selection Notes

Select this part only if the specific 10 MHz to 1.3 GHz frequency range and 20 dB dynamic range align with system requirements. The 16-QSOP package requires compatible PCB footprints. Consider that the obsolete status necessitates immediate substitution analysis for long-term projects. Verify that the 4.8 V to 5.2 V supply range matches existing power architectures.
