4-Channel 600 MHz Dual-Balanced InGaAs Low Noise Photodetector

  In stock

The BPD600MA-QUAD is an AC-coupled high-speed dual-balanced InGaAs photoreceiver. It houses 4 independent differential channels in a single space-saving case. Due to its high transimpedance gain, its very low noise, and its bandwidth of 600 MHz, it is ideally suited for multi-channel interferometry or LIDAR systems.

The BPD600MA-QUAD comes in a rugged aluminum case with 8 FC fiber receptables and four 50 Ω coupled SMA outputs. It operates from a dual 11-15 V DC supply.
