Procurement Notes

Verify part authenticity through authorized channels as this component may be subject to obsolescence notices. Confirm RoHS compliance status and check for specific manufacturing date codes or packaging variations before procurement. Ensure supply chain stability due to potential discontinuation risks associated with legacy RF components.

Selection Notes

Select this component for S-band applications requiring 25 W output power. Verify that the system design supports the 65 V drain voltage rating and 900 mA operating current. Ensure thermal management solutions are compatible with the CDFM6 base-mount package geometry and heat dissipation requirements.

Part Context

This transistor belongs to the BLF8/BLF7 series of LDMOS devices from Ampleon. These components are engineered for high-efficiency RF power amplification. The BLF7G27L-135 variant specifically targets the 2.5–2.7 GHz band, distinguishing it from other models in the family that may operate at different frequencies or power levels.

Replacement Considerations

No official substitute part numbers are documented for this specific model. Evaluate cross-compatibility with other BLF7 or BLF8 series transistors only if pinout, package dimensions, and electrical parameters match exactly. Consult manufacturer documentation for any approved replacements.
