BLF8G20LS-200V,115

Overview

The BLF8G20LS-200V is a 200 W LDMOS power transistor designed for base station applications in the 1800 MHz to 2000 MHz frequency range. It features improved video bandwidth and low memory effects, making it suitable for multi-carrier systems. The device operates at a drain-source voltage of 28 V with a quiescent current of 1600 mA. In typical 2-carrier W-CDMA operation, it delivers an average output power of 55 W with a gain of 17.5 dB and a drain efficiency of 33%. The transistor is housed in an earless flanged SOT1120B ceramic package.

Feature Summary

• Integrated ESD protection for robust handling

Applications

• RF power amplifiers for W-CDMA base stations
• Multi-carrier applications in the 1800 MHz to 2000 MHz frequency range

Procurement Notes

Verify component authenticity through authorized Ampleon channels or certified distributors. Confirm RoHS compliance status and check for any product change notices (PCN) related to manufacturing site changes. Ensure proper electrostatic discharge precautions are observed during storage and handling due to integrated ESD protection limitations.

Selection Notes

Select this component for wideband code division multiple access transmitter stages requiring high linearity and ruggedness. Evaluate thermal management requirements based on the junction-to-case thermal resistance. Ensure the application supports the specified 28 V drain supply and 1600 mA quiescent current operating conditions for optimal performance.
