Description

Product Overview

The BFR540 is an NPN silicon epitaxial transistor designed for microwave low-noise amplification. It offers high power gain, wide bandwidth, low noise, low leakage current, small junction capacitance, and a large dynamic range with good current linearity. This transistor is ideal for applications in ultra-high frequency microwave, VHF, UHF, and CATV high-frequency wideband low-noise amplifiers. Typical applications include satellite TV tuners, CATV amplifiers, analog and digital cordless phones, radar detectors, wireless security alarms, RF modules, and repeater amplifiers in fiber optic transmission systems.
