Procurement Notes

Verify the specific suffix against official Ampleon documentation to confirm package type and reel specifications. Ensure compatibility with existing thermal management designs. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement orders.

Selection Notes

Select this component for applications requiring approximately 500 W output power in the 617-960 MHz range. Compare its 50 mOhm on-resistance and 18.2 dB gain against alternative models like the BLC9H10XS-600A if higher power or different packaging is required. Verify that the SOT1273-1 footprint fits the target PCB layout constraints.

Part Context

This part belongs to Ampleon's BLC9H10XS series of UHF LDMOS transistors. These devices are engineered for high-efficiency linear amplification in broadcast and communication infrastructure. The series offers various power levels and package options to suit different transmitter architectures and thermal requirements.

Replacement Considerations

The BLC9H10XS-600A is a documented variant within the same family offering 600 W output power. It utilizes the SOT1250-2 package, which differs physically from the SOT1273-1 used by the BLC9H10XS-505AY. Direct pin-to-pin replacement is not possible due to the package difference.
