BeRex Granted Patent for Operating Condition Adjustment Method for Power Amplifier Using FIB

SANTA ANA, Calif. - Sept. 8, 2025 - PRLog -- BeRex, Inc. is pleased to announce that it has been granted a patent for its innovative technology titled " POWER AMPLIFIER AND METHOD FOR CONTROLLING OPERATING CONDITIONS OF POWER AMPLIFIER USING FOCUSED ION BEAM PROCESS" This newly issued patent strengthens BeRex's RF IC design portfolio.

"This patent enables us to adjust the operating point of RF power amplifiers more flexibly, reducing development time and costs while providing both performance and power efficiency improvements," said Taewon Jung, Design Lead at BeRex, Inc. "We are proud to bring this breakthrough technology to the global RF market and further enhance our competitive edge."

The key innovation of this technology lies in its ability to achieve two-way control of power amplifier operating conditions. Traditional adjustment methods allowed only one-way control, lowering both output power and power consumption. By leveraging the precision of the FIB process, this new approach makes it possible not only to reduce but also to increase the gate voltage of the input stage. Specifically, the method enables fine control of the current source that sets the gate voltage: instead of disconnecting the source or drain, the process can selectively remove the resistor connected to the gate, thereby allowing both upward and downward adjustments.

This innovation provides a practical means of balancing output power and current consumption in RF power amplifiers, ultimately improving efficiency and design flexibility.

BeRex, Inc. remains committed to advancing technology and delivering cutting-edge solutions to meet the evolving needs of its customers. With this patent, the company continues to strengthen its position as a leader in the RF amplifier market.
