Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to limited availability status. Confirm RoHS compliance and moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Ensure soldering profiles match the leadless ceramic package specifications to prevent thermal damage. Cross-reference datasheet revisions to confirm electrical parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when requiring ultra-wideband amplification from DC to 20 GHz with low noise characteristics. Consider the 13 dB gain and 3.5 dB noise figure for sensitive receiver front-ends. Evaluate the 8 V supply requirement against system power constraints. The 5 x 5 mm ceramic package suits applications demanding robust thermal management in dense PCB layouts compared to standard plastic packages.
