Overview
The BLF8G20LS-400PGVJ 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 video bandwidth of 120 MHz typical. 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 2-carrier W-CDMA conditions. The component 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 against official Ampleon documentation to confirm lead configuration and packaging details. Ensure compliance with ESD handling standards during storage and assembly. Confirm RoHS directive compliance status prior to integration into final designs.
Selection Notes
Select this component for broadband operations requiring high efficiency and low memory effects. Evaluate impedance matching networks using provided load-pull data for optimal performance. Consider the SOT1242C package dimensions for PCB layout constraints.
Part Context
This part belongs to the BLF8G20LS series of power LDMOS transistors manufactured by Ampleon USA Inc. The 'PGV' designation indicates the specific gull-wing lead variant within the LS-400 product family, distinct from the straight lead PV version.
Replacement Considerations
The BLF8G20LS-400PV serves as the straight-lead alternative within the same datasheet. Verify pinout compatibility and mechanical footprint differences before substitution.
