BCF030T

Overview

The BeRex BCF030T is a Gallium Arsenide (GaAs) Power MESFET chip featuring a nominal 0.3 micron gate length and 300 micron gate width. Designed for high OIP3 linearity and low phase noise, it delivers high gain and medium power across DC to 26.5 GHz. At 12 GHz with Vds=8V, typical output power reaches 21.5 dBm with 13.5 dB gain. The device utilizes SI 3N4 passivation for reliability and requires Au-Sn eutectic die attach. Maximum ratings include a drain-source voltage of 12V and total power dissipation of 1.2W.

Procurement Notes

Verify the specific revision status of the datasheet prior to design finalization, as specifications are subject to change without notice. Confirm that the procurement channel provides authentic BeRex Inc components. Ensure handling procedures strictly adhere to ESD precautions and clean room requirements during assembly to prevent damage to the sensitive GaAs structure.

Selection Notes

Select this component when high OIP3 linearity and low phase noise are critical system requirements. It is appropriate for designs requiring medium power output up to 26.5 GHz. Designers must account for the bare chip format, necessitating custom wire bonding and die attach processes using recommended Au-Sn pre-forms and inert gas environments.

Part Context

The BCF030T belongs to the BeRex family of high-efficiency heterojunction power FETs. These devices utilize state-of-the-art metallization and are screened on each wafer to ensure reliability. The product line targets applications where superior linearity and noise performance are prioritized over maximum power density in the microwave frequency range.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult BeRex technical support for direct equivalents or cross-reference options based on specific electrical constraints.

FAQ

What is the recommended die attach method for the BCF030T?

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

How does the BCF030T handle electrostatic discharge risks?

GaAs FETs are highly sensitive to ESD. Proper ESD precautions are critical, including grounding all work surfaces, assembly equipment, and operators. Devices should be stored in antistatic Gel-Pak packaging within sealed moisture barrier bags.

What are the maximum continuous ratings for the BCF030T?

The absolute maximum continuous ratings include a Drain-Source Voltage of 12V, Gate-Source Voltage of -8V, and Total Power Dissipation of 1.2W. Exceeding these may cause permanent damage.
