BLF8G27LS-150GVJ

Overview

The BLF8G27LS-150GVJ is a 150W LDMOS power transistor designed for base station applications in the 2500 MHz to 2700 MHz frequency range. It features improved video bandwidth and low memory effects, making it suitable for digital pre-distortion. The device operates at a drain-source voltage of 28 V with a typical quiescent current of 1300 mA. In a common source class-AB test circuit, it delivers an average output power of 45 W with a gain of 18 dB and drain efficiency of 30%. The component utilizes an earless flanged ceramic package (SOT1244C) with six leads.

Feature Summary

• Decoupling leads enable improved video bandwidth for enhanced signal fidelity
• Lower output capacitance improves performance in Doherty amplifier configurations
• Designed for low memory effects to support excellent digital pre-distortion capability
• Internally matched structure simplifies circuit integration

Applications

• RF power amplifiers for W-CDMA base stations
• Multi-carrier applications in the 2500 MHz to 2700 MHz frequency range
• Doherty amplifier architectures requiring low output capacitance

Procurement Notes

Verify the specific ordering suffix GVJ against the manufacturer's official documentation to confirm the SOT1244C package variant. Ensure that the procurement channel provides original manufacturer data sheets to validate the product status and revision history before finalizing orders.

Selection Notes

Select this component for wideband base station designs requiring high ruggedness and thermal stability. The internal matching reduces external component count, while the decoupling leads facilitate high video bandwidth requirements essential for modern digital modulation schemes like 3GPP Test Model 1.

Part Context

This part belongs to the BLF8G27LS series of LDMOS transistors from Ampleon USA Inc. The 'GV' suffix typically denotes the specific lead frame configuration (SOT1244C) compared to the standard 'V' version (SOT1244B). Both variants share identical electrical characteristics but differ in physical pinning and mechanical outline dimensions.

Replacement Considerations

The BLF8G27LS-150V is the primary alternative within the same family. It shares identical RF and DC specifications but utilizes the SOT1244B package. Verify mechanical footprint compatibility when substituting between the V and GV versions.
