270 MHz Dual-Balanced InGaAs Low Noise Photodetector

  In stock

The BPD270MA5 is an AC-coupled high-speed dual-balanced InGaAs photoreceiver. It features a high transimpedance gain, very low noise and a -3 dB bandwidth of 270 MHz. The low frequency AC cutoff is set to >5 MHz to help suppress low frequency noise like acoustic vibrations.

The BPD270MA5 comes in a rugged aluminum case with two FC fiber receptables and a 50 Ω coupled SMA output. It operates from a single 11-15 V DC supply.

OEM versions without a case are available upon request.
