Procurement Notes

This component carries an NRND status, indicating it is not recommended for new designs. Verify current availability through authorized distributors as stock levels fluctuate. Confirm RoHS compliance details via official documentation before integration. Check for any recent discontinuation notifications or end-of-life updates from STMicroelectronics to ensure long-term supply chain viability.

Selection Notes

Select this part for high-power applications requiring operation between 0.4 and 1 GHz. Ensure the design supports 50 V drain biasing and accommodates the specific thermal requirements for 650 W output. Consider the internal matching network which simplifies circuit design but limits impedance flexibility compared to unmatched devices. Verify that the application environment aligns with the specified temperature ranges and humidity sensitivity classifications.
