BLF7G27L-75P,118

Overview

The BLF7G27L-75P is a 75 W LDMOS power transistor designed for base station applications in the 2300 MHz to 2700 MHz frequency range. It operates with a drain-source voltage of 65 V and features an internally matched design for ease of use. The device provides typical power gain of 17 dB, drain efficiency of 26%, and average output power of 12 W under single carrier IS-95 conditions at 28 V. It includes integrated ESD protection and exhibits excellent ruggedness, capable of withstanding a VSWR of 10:1 through all phases.

Feature Summary

• Internally matched for simplified circuit integration
• Low thermal resistance ensuring stable operation
• Integrated electrostatic discharge (ESD) protection
• Optimized low memory effects for pre-distortion compatibility

Applications

• RF power amplifiers for W-CDMA base stations
• Multi-carrier applications in the 2300 MHz to 2700 MHz range
• Single carrier IS-95 systems with pilot, paging, sync, and traffic channels

Procurement Notes

Verify the specific package variant required for the target application. The BLF7G27L-75P corresponds to the SOT1121A flanged ceramic package with mounting holes, while the BLF7G27LS-75P uses the SOT1121B earless flanged package. Confirm RoHS compliance status and ensure sourcing from authorized Ampleon distributors to guarantee product authenticity and datasheet accuracy.

Selection Notes

Select this component for broadband RF power amplifier designs operating between 2300 MHz and 2700 MHz. The device is optimized for Doherty configurations due to its lower output capacitance. Ensure the design accommodates the 65 V drain-source voltage limit and utilizes appropriate heat sinking to manage the junction-to-case thermal resistance effectively during high-power operation.

Part Context

This part belongs to the Ampleon BLF7G series of LDMOS power transistors. It is specifically engineered for wireless infrastructure, offering high efficiency and ruggedness suitable for demanding base station environments. The device represents a mature technology solution for 3G and multi-carrier communication systems requiring reliable linear amplification.

Replacement Considerations

The BLF7G27LS-75P serves as a direct functional equivalent with a different mechanical footprint (SOT1121B vs. SOT1121A). When substituting, verify that the PCB layout supports the specific pin configuration and mounting requirements of the replacement package variant.
