Procurement Notes

Verify the current lifecycle status before procurement, as this component may be classified as obsolete or end-of-life. Confirm that the Micro-P package availability aligns with manufacturing requirements. Ensure compatibility with existing PCB footprints if replacing active inventory. Check for official product change notices regarding material or process updates. Validate that the specific MP86 suffix meets all design specifications for the target application.

Selection Notes

Select this component when a broadband DC-to-5 GHz gain stage is required in a compact surface-mount form factor. Consider the 12 dB gain and 14 dBm P1dB characteristics for moderate linearity needs. Evaluate the 702 mW power dissipation against thermal management capabilities in the final assembly. Compare noise figure requirements against other available gain blocks if low-noise performance is critical.
