Procurement Notes

Verify the specific package type and pinout configuration against the official MACOM datasheet prior to PCB layout finalization. Confirm that the mounting hardware requirements align with the screw mount specification. Ensure thermal management solutions are adequate for the specified +200°C maximum junction temperature rating during system design validation.

Selection Notes

Select the DU2805S when designing circuits requiring 10 W output power below 175 MHz. Consider its 65 V breakdown voltage for systems operating near or above standard 28 V rails. Evaluate the screw mount interface against available board space and mechanical constraints compared to surface-mount alternatives.
