CLF3H0035S-100U

Overview

The CLF3H0035S-100U is a 100 W general-purpose, unmatched broadband Gallium Nitride High Electron Mobility Transistor (GaN HEMT) manufactured by Ampleon. It operates in the frequency range from DC to 3.5 GHz and utilizes a thermally enhanced SOT467B earless ceramic package suitable for both continuous wave and pulsed applications. The device features a drain-source voltage rating of 150 V and a maximum active die channel temperature of 300 °C. Typical performance at Tcase = 25 °C, VDS = 50 V, and IDq = 160 mA includes an output power of 118 W at PL(3dB), a power gain of 14 dB at 100 W output, and a drain efficiency of 52% at 100 W output.

Feature Summary

• Broadband operation capability spanning from DC to 3.5 GHz
• High efficiency with low thermal resistance design
• Excellent ruggedness supporting Class-AB operation under load mismatch conditions

Applications

• General purpose RF power amplification
• Broadband communication systems
• Pulsed and continuous wave RF applications

Procurement Notes

Verify the specific ordering suffix 'U' corresponds to the tray packing description provided in the official documentation. Confirm that the SOT467B package variant matches the required mechanical footprint for the target application. Ensure compliance with ESD handling standards C2B and 1A as specified in the datasheet to prevent device damage during assembly.

Selection Notes

Select this component when a high-power GaN HEMT solution is required for broadband frequencies up to 3.5 GHz. The SOT467B package is appropriate for designs requiring an earless ceramic configuration. Consider the thermal management requirements associated with the 1.6 K/W thermal resistance from channel to case for sustained operation.

Part Context

The CLF3H0035S-100U belongs to the CLF3H0035 series of general-purpose broadband GaN HEMTs from Ampleon. It shares core electrical specifications with the flanged SOT467C variant but differs in package style. This series is designed to provide high power density and efficiency across a wide frequency spectrum for RF engineering applications.

Replacement Considerations

The CLF3H0035-100U serves as the functional equivalent within the same product family, differing primarily in the SOT467C flanged package instead of the SOT467B earless package. Verify mechanical mounting constraints before substitution.
