BLF8G20LS-220J

Overview

The BLF8G20LS-220 is a 220 W LDMOS power transistor designed for base station applications operating between 1800 MHz and 2000 MHz. It utilizes an earless flanged ceramic package (SOT502B) with two leads. The device operates at a drain-source voltage of 28 V with a quiescent current of 1600 mA, delivering 55 W average output power in a 2-carrier W-CDMA test configuration. Key electrical parameters include a typical power gain of 18.9 dB, a drain efficiency of 34%, and a thermal resistance from junction to case of 0.27 K/W.

Feature Summary

• Excellent ruggedness capable of withstanding high load mismatch conditions
• Low thermal resistance providing excellent thermal stability
• Lower output capacitance optimized for improved performance in Doherty applications
• Internally matched design for ease of use

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Ampleon documentation to ensure correct package version and compliance status. Confirm that the component meets RoHS Directive 2002/95/EC requirements before integration. Ensure proper ESD handling protocols are followed during storage and assembly due to electrostatic sensitivity.

Selection Notes

Select this component for broadband RF power amplifier designs requiring high efficiency and low memory effects. Verify that the application circuit supports the specified 28 V drain voltage and 1600 mA quiescent current. Ensure the host system provides adequate heat sinking to maintain the junction temperature below the 225 °C maximum limit under continuous operation.
