BLF6G27-75,112

Overview

The BLF6G27-75,112 is a dual-channel LDMOS RF power transistor manufactured by Ampleon USA Inc. Designed for high-efficiency performance in the VHF band, this component utilizes an SOT467C flange-mount package to facilitate robust thermal dissipation. It operates with a rated drain-source voltage of 65V and delivers a typical output power of 75W at 2GHz. The device features a gain of approximately 13.5dB and is tested at a drain voltage of 26V with a current of 450mA. This transistor is engineered for linear amplification applications requiring stable operation within its specified frequency range.

Feature Summary

• Dual-channel configuration providing independent signal paths within a single package
• LDMOS technology optimized for high linearity and efficiency in RF amplification
• Flange-mount construction designed for effective heat transfer to heatsinks

Applications

• Commercial broadcast transmission systems
• VHF radio communication infrastructure
• Industrial heating and plasma generation equipment

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging variations. Confirm end-of-life status or obsolescence notices prior to procurement planning. Ensure compatibility with existing thermal management solutions given the flange-mount requirement. Request latest datasheets to validate pinout assignments and absolute maximum ratings for circuit design safety.

Selection Notes

Select this component when designing circuits operating in the VHF spectrum requiring moderate power levels around 75W. Evaluate the thermal resistance characteristics of the SOT467C package against your system's cooling capabilities. Compare the 65V rating with your supply voltage headroom requirements. Consider the dual-channel architecture if space constraints necessitate integrating two amplifier stages into one footprint.

Part Context

This part belongs to the BLF series of LDMOS transistors from Ampleon, a division historically associated with NXP Semiconductors' RF Power division. The series is widely recognized for reliability in broadcast and industrial RF applications. The BLF6G27 variant specifically targets the VHF band, offering a balance between power density and linearity suitable for analog and digital modulation schemes common in professional broadcasting.

Replacement Considerations

Direct cross-compatibility should be verified using official substitution guides. Check pin-to-pin equivalents within the same manufacturer portfolio that match the 75W output and 65V rating. Ensure replacement devices support the SOT467C mechanical outline. Validate that any substitute maintains similar gain and linearity specifications for the target frequency.
