BLF6G20S-45,118

Overview

The BLF6G20S-45 is a 45 W LDMOS power transistor designed for base station applications in the 1800 MHz to 2000 MHz frequency range. It operates with a drain-source voltage of 65 V and features an internal matching network. In typical two-carrier W-CDMA operation at 1805 MHz and 1880 MHz, it delivers 2.5 W average output power per carrier with 19.2 dB gain and 14% efficiency. The device utilizes a ceramic earless flanged SOT608B package.

• Internally matched for ease of use
• Integrated ESD protection
• Excellent ruggedness
• High efficiency

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 confirm package type and compliance status. Ensure that the component meets all relevant environmental directives before integration into final designs.

Selection Notes

Select this component for broadband operations requiring high thermal stability and easy power control within the specified frequency band. Confirm that the application circuit supports the required quiescent current and supply voltage conditions for optimal performance.

Part Context

This part belongs to the BLF6G20 series of LDMOS power transistors manufactured by Ampleon USA Inc. The 'S' designation indicates the specific SOT608B earless flanged package variant, distinct from the standard flanged version.

Replacement Considerations

Consult official Ampleon documentation for confirmed substitute part numbers. Verify pinout compatibility and thermal resistance specifications when evaluating alternative components for existing designs.
