首页 PhotoDetectors Balanced photodetector InGaAs balanced photodetector Indium Gallium Arsenide InGaAs Optoelectronic Balance Detector MBD-A Series 800-1700nm InGaAs photobalanced detector MBD-1.5G-A

    • InGaAs photobalanced detector MBD-1.5G-A

    The high-speed low-noise photoelectric balanced detection module integrates two matched low-noise analog PIN detectors, a low-noise broadband transimpedance amplifier and an ultra-low noise power supply. It has the characteristics of high gain, high sensitivity, high bandwidth, low noise, high common mode rejection ratio, etc. It can effectively reduce the common mode noise of the signal and improve the signal-to-noise ratio of the system.

    产品特点Low noise、 High gain、 High bandwidth、 Compact structure、 Built-in low noise isolated power supply
