BLF8G27LS-150VJ

Overview

The BLF8G27LS-150VJ 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 quiescent current of 1300 mA. In a typical class-AB production test circuit, it delivers an average output power of 45 W with a gain of 18 dB and a drain efficiency of 30%. The component utilizes an earless flanged ceramic package (SOT1244B) and includes integrated ESD protection.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package variant. The standard datasheet lists the BLF8G27LS-150V as the primary part number associated with the SOT1244B earless flanged ceramic package. Ensure that any additional characters in the requested model number correspond to verified packaging or handling specifications provided by Ampleon USA Inc.

Selection Notes

Select this component for high-efficiency linear amplification in cellular infrastructure. The device requires careful thermal management due to its junction-to-case thermal resistance characteristics. Designers must account for the internal matching network when designing input and output impedance circuits. Verify that the application environment adheres to the specified absolute maximum ratings for drain-source voltage and gate-source voltage limits.

Part Context

This transistor belongs to the BLF8G27LS series from Ampleon, specifically engineered for broadband wireless communication systems. The series addresses the need for robust performance in modern base station architectures. The BLF8G27LS-150V variant serves as the baseline for this family, offering a balance of power output and linearity for wideband code division multiple access technologies.

Replacement Considerations

The BLF8G27LS-150GV is a documented alternative within the same product family. It shares identical electrical specifications but utilizes the SOT1244C package outline. Engineers should verify mechanical footprint compatibility before substituting one variant for the other.
