Procurement Notes

Verify the specific revision level against the latest official datasheet before procurement, as packaging details may have been updated. Confirm that the required test fixtures are available, as they are necessary for proper evaluation and integration. Ensure that the supply chain documentation aligns with current export classification standards, specifically EAR-99, to prevent compliance issues during international shipping.

Selection Notes

Select this component when designing avionics secondary radar systems requiring high peak power in the 1030-1090 MHz band. The 50V bias requirement and specific gate-source voltage limits must be accommodated in the driver circuit design. Consider the thermal resistance and junction temperature limits when planning heat dissipation strategies for the 55-QP package.
