FPD310
High Sensitivity Fast PIN Photodetector
The high sensitivity ultrafast PIN photodetector FPD310 product family is optimized for high gain, high bandwidths, extremely short rise times and high signal-to-noise ratio. These photodetectors are easy-to-use Si- or InGaAs-PIN photodiode pack-ages with an integrated high gain, low noise RF amplifier.
The gain can be switched between two fixed settings (0 dB and 20 dB attenuation), which allows an optimal performance for the user’s application.
Models for both visible and near infrared range are available, both with either free space or fiber coupled optical input. The compact design of these detectors allows for easy OEM integration. Included with each amplified photodetector is a low noise power supply, which features a universal AC input.
The units are especially recommended for applications like pulse shape and low-noise radio frequency extraction.
