BLF8G20LS-400PGVQ

Overview

The BLF8G20LS-400PGV is a 400 W LDMOS power transistor designed for base station applications in the 1805 MHz to 1995 MHz frequency range. It features decoupling leads that provide an improved typical video bandwidth of 120 MHz. The device operates at a drain-source voltage of 28 V with a quiescent current of 3400 mA, delivering 95 W average output power. Typical performance includes a power gain of 19 dB and a drain efficiency of 28% under two-carrier W-CDMA test conditions. It utilizes an earless flanged ceramic package (SOT1242C) with gull-wing leads.

Feature Summary

• Decoupling leads enable improved video bandwidth for enhanced signal fidelity
• Low thermal resistance provides excellent thermal stability
• Lower output capacitance improves performance in Doherty configurations
• Designed for low memory effects to facilitate pre-distortion

Applications

• RF power amplifiers for base stations
• Multi-carrier applications in the 1805 MHz to 1995 MHz range

Procurement Notes

Verify the specific ordering suffix PGV to confirm the gull-wing lead configuration, as the datasheet also covers the PV variant with straight leads. Ensure compliance with ESD handling standards during assembly. Confirm RoHS directive compliance requirements for the target market before finalizing procurement specifications.

Selection Notes

Select this component for high-efficiency broadband RF power amplification where low memory effects are critical. Verify that the application circuit can support the required 28 V supply and 3400 mA bias current. Ensure the design accommodates the SOT1242C package dimensions and thermal management needs for continuous operation.

Part Context

This part belongs to the Ampleon BLF8G series of LDMOS transistors. The LS designation indicates optimized linearity and video bandwidth characteristics compared to standard variants. The PGV suffix specifically denotes the gull-wing lead version within the earless flanged ceramic package family.

Replacement Considerations

The BLF8G20LS-400PV is the electrically equivalent alternative featuring straight leads instead of gull-wing leads. Substitution requires verification of mechanical footprint compatibility and PCB layout adjustments for the different lead styles.
