Procurement Notes

Verify the specific ordering suffix when sourcing components. The datasheet indicates that the standard supply form is embossed taping, while sample orders utilize the -AZ suffix. Confirm the exact part number required for your manufacturing process against the manufacturer's official ordering information to ensure correct packaging and availability status.

Selection Notes

Select this component for designs requiring Class-AB operation in the VHF to UHF frequency bands. Ensure the circuit design accommodates the recommended operating range of 7.5V to 9.0V for VDS. Consider the thermal resistance characteristics and the need for appropriate heat dissipation given the total power dissipation rating. Verify impedance matching networks align with the specified test frequencies for optimal performance.

Part Context
