Product Description

Product Overview

The BFU590Q is an NPN silicon epitaxial transistor designed for microwave low-noise amplifier applications. Manufactured using silicon epitaxial process technology, it offers high power gain, wide bandwidth, low noise, low leakage current, and small junction capacitance. Its large dynamic range and excellent current linearity make it ideal for UHF microwave and high-frequency broadband low-noise amplifiers. Typical applications include CATV video amplifiers, wireless transceiver modules, remote control systems, security alarms, and analog/digital cordless phones, suitable for medium-power high-frequency signal amplification.
