BLF8G27LS-150VU

Overview

The BLF8G27LS-150VU is an LDMOS power transistor designed for base station applications in the 2500 MHz to 2700 MHz frequency range. It delivers a typical output power of 45 W at a drain efficiency of 30% under two-carrier W-CDMA conditions (VDS = 28 V, IDq = 1300 mA). The device features a maximum drain-source voltage of 65 V and a junction temperature limit of 225 °C. It utilizes a flanged ceramic package (SOT1244B or SOT1244C) with six leads, including decoupling leads to enhance video bandwidth.

Feature Summary

• Decoupling leads enable improved video bandwidth for digital pre-distortion capability
• Lower output capacitance improves performance in Doherty applications
• Internally matched design simplifies circuit integration
• Integrated ESD protection ensures handling safety

Applications

• RF power amplifiers for W-CDMA base stations
• Multi-carrier applications in the 2500 MHz to 2700 MHz range
• Amplifiers requiring low memory effects

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the exact package variant (e.g., SOT1244B vs. SOT1244C) and compliance status. Confirm that the component meets the required environmental directives before finalizing procurement specifications.

Selection Notes

Select this component for designs operating between 2500 MHz and 2700 MHz requiring high linearity and ruggedness. Ensure the thermal management system can maintain the case temperature within limits to support the specified 45 W output power and 30% drain efficiency in class-AB operation.

Part Context
