PD11 AC Coupled High-Speed Photodetector - 1000-1700nm InGaAs, 1GHz Bandwidth

Product Overview

PD11 is a professional AC coupled high-speed photodetector exclusively designed for ultra-fast near-infrared optical signal detection and high-precision fiber optical system integration. Based on high-quality InGaAs core material, it features a broad 1000-1700nm spectral response range with an excellent responsivity of 0.9A/W @1550nm, ensuring ultra-sensitive conversion of weak near-infrared light signals into electrical signals. The detector integrates a high-speed photodiode, low-noise transimpedance amplifier and high-frequency RF connector in a rugged, compact aluminum housing, with a standard FC fiber flange input for effortless coupling with FC optical cables and SMA female output optimized for miniaturization and maximum high-frequency response performance. Boasting an ultra-wide 1GHz bandwidth (400k-1GHz) and an ultra-fast 400ps rise time, the PD11 excels in capturing ultra-fast dynamic optical signals such as high-speed laser pulses and heterodyne laser beat signals. With 50Ω output impedance matching, low noise performance and stable operation across a -20~65℃ temperature range, this AC coupled photodetector is a reliable and high-performance solution for academic research, laboratory optical experiments and industrial high-speed optical detection applications.
