RF Detectors Procurement Notes

Verify the specific suffix (G vs GE) against the manufacturer's official discontinuation notices, as availability may be limited. Confirm RoHS compliance status directly from the latest datasheet, as some listings indicate non-compliance. Ensure the procurement channel provides valid traceability for this end-of-life product. Check for updated replacement recommendations from Analog Devices before finalizing orders.

RF Detectors Selection Notes

Select this component when ultra-low phase noise is critical for the application's signal integrity. The 10 MHz to 1.3 GHz operating range suits general-purpose RF designs. Consider the 96 mA supply current for power budget calculations. The QSOP-16 package requires appropriate PCB footprint design due to the exposed pad for thermal management and electrical connection.
