BCF060T

Overview

The BeRex BCF060T is a GaAs Power MESFET chip featuring a 0.3 µm gate length and 600 µm gate width, designed for high OIP3 linearity and low phase noise from DC to 26.5 GHz. At 12 GHz with Vds = 8V, it delivers 25.0 dBm output power, 12.5 dB gain, and 32% PAE. At 18 GHz under the same bias, output power is 24.6 dBm, gain is 10.0 dB, and PAE is 31%. Maximum ratings include a 12 V drain-source voltage, -8 V gate-source voltage, and 1.9 W total power dissipation at 175°C channel temperature.

• High-efficiency heterojunction design utilizing state-of-the-art metallization and SI 3N4 passivation for enhanced reliability.
• Optimized for wideband or narrow-band applications requiring high linearity and low phase noise.
• Integrated advanced protection features including anti-cross-conduction, deadtime, and UVLO functions.

Applications

• Commercial RF systems
• Military and Hi-Rel equipment
• Test & Measurement instruments

Procurement Notes

Verify component authenticity by cross-referencing the datasheet revision (Rev. 1.4a) and manufacturer details with official BeRex documentation. Ensure handling procedures strictly follow ESD precautions and clean room requirements due to the sensitive nature of the GaAs material. Confirm that all electrical parameters align with your specific system bias conditions before integration.

Selection Notes

Select this component when designing circuits operating between DC and 26.5 GHz that demand high linearity and low phase noise. Consider the 0.3 µm gate length for performance optimization. Evaluate thermal management capabilities against the specified thermal resistance of 75 °C/W and maximum channel temperature limits to ensure reliable operation within the defined voltage and current constraints.

Part Context

This device belongs to the BeRex GaAs Power MESFET family, specifically engineered for high-frequency applications. It represents a specialized semiconductor solution focusing on linear amplification and signal integrity in microwave and millimeter-wave bands, distinct from standard digital or low-frequency analog components.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Designers should consult BeRex directly for potential alternatives or updated product lines if this specific chip becomes unavailable.

FAQ

What is the recommended die attach method?

BeRex recommends using 'Eutectic' die attach with Au-Sn (80%-20%) pre-forms, performed at temperatures no hotter than 300°C for less than 60 seconds in an inert forming gas or clean, dry nitrogen environment.

How does the BCF060T handle electrostatic discharge?

GaAs FETs like the BCF060T are highly sensitive to ESD. Proper grounding of all work surfaces, assembly equipment, and operators is critically important to prevent damage during handling and assembly.

What are the storage and shipping conditions?

Chips are shipped in antistatic Gel-Pak containers inside sealed antistatic and moisture barrier bags. They should be stored in a clean, dry nitrogen gas environment at room temperature until assembly.
