Procurement Notes

Verify the specific suffix (e.g., LP3E) against the official datasheet to ensure correct pinout and electrical specifications. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability. Ensure the selected package variant matches the PCB footprint requirements exactly.

Selection Notes

Select this component when designing circuits requiring low noise amplification between 5 GHz and 10 GHz. Consider the 3.5 V supply requirement and 80 mA current consumption for power budgeting. Evaluate the thermal dissipation capabilities relative to the QFN-16 package size. Compare the noise figure and gain specifications against system link budget requirements to ensure adequate signal integrity.
