BeRex Granted Patent for Enhanced Linearity in a Cascode Amplifier

Share Article

BeRex today announces that it has been assigned U.S. Patent US 8,493,154 B1 that provides for enhanced linearity for a cascode gain block amplifier.

This patent US 8,493,154 B1 describes a cascode amplifier circuit having substantial enhanced linearity, while maintaining other advantages of cascode amplifiers such as relatively high input-to-output isolation and relatively high gain. The cascode amplifier circuit also provides substantially matched impedance between input and output, at least within a selected frequency band, with the effect of providing a circuit that is well-suited for use in a communication system. The cascode amplifier circuit included feedback loops, such as for example DC feedback loops and AC feedback loops, and bias optimization, with the effect of improving linearity, maintaining gain, minimizing return loss, and providing relatively high dynamic range.

Dr. Alex Yoo, Vice President of Engineering for BeRex stated, “This patent further strengthens BeRex’s technological differentiation and provides our clients a clear advantage.”
