ART150FEU

Overview

The ART150FEU is a dual N-channel LDMOS RF power transistor manufactured by Ampleon. It operates within a frequency range of 1 MHz to 650 MHz and delivers an output power of 150 W per channel. The device features a drain-source breakdown voltage (Vds) of 65 V and a typical on-resistance (Rds(on)) of 497 mOhms. It provides a gain of 31.2 dB and supports a maximum operating temperature of +225°C. Packaged in the SOT1121A-5 form factor for screw mounting, this component is designed for robust performance in high-frequency radio applications.

Feature Summary

• Dual N-channel configuration utilizing Advanced Rugged Technology (ART) for enhanced durability
• Integrated dual-sided ESD protection enabling Class C operation and complete switch-off capability
• High thermal stability and excellent ruggedness with no device degradation under stress

Applications

• Industrial, Scientific, and Medical (ISM) equipment such as plasma generators and particle accelerators
• Broadcast systems including FM radio transmitters and DVB-T digital television transmission
• Communication infrastructure requiring broadband RF amplification

Procurement Notes

Verify the specific suffix 'U' against the manufacturer's official documentation to confirm packaging details, as standard variants may utilize different reels or trays. Ensure compliance with RoHS directives and check moisture sensitivity levels prior to surface mount processing. Confirm that the SOT1121A-5 package matches your thermal management design requirements.

Selection Notes

Select this component when a dual-channel solution is required for frequencies up to 650 MHz. The 65 V breakdown voltage supports Class E operation up to 53 V. Consider the 497 mOhm on-resistance for efficiency calculations. Verify that the screw-mount SOT1121A-5 package fits your mechanical constraints compared to surface-mount alternatives.

Part Context

This part belongs to the ART series of LDMOS transistors from Ampleon, which are engineered for high reliability in demanding RF environments. The series covers various power levels, with the ART150FEU serving as a mid-power dual-channel option suitable for both broadcast and industrial ISM bands.

Replacement Considerations

Consult Ampleon's official cross-reference lists for verified substitutes. Generic replacements may not match the specific ART ruggedness or ESD protection characteristics. Verify pinout compatibility and thermal resistance values before substitution.
