Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and variant selection. Confirm that the TO-270BA footprint matches your PCB layout requirements. Check for any recent updates to the RoHS compliance status or lead times directly with authorized distributors before finalizing procurement orders.

Selection Notes

Select this component when a 25 W output power level is required at frequencies up to 941 MHz. Ensure the design supports a 13.6 V supply rail and accommodates the thermal dissipation needs of the TO-270BA package. Consider the 18.4 dB gain characteristic for system-level power budget calculations and impedance matching network design.

Part Context

This part belongs to Ampleon's portfolio of LDMOS transistors, which are widely used in RF infrastructure. The BLP9LA25SGXY represents a specific configuration optimized for medium-power applications, balancing gain, efficiency, and ruggedness.
