Electro Optical Components, Inc. 400 MHz High Speed Photoreceivers HCA-S-400M

The series HCA-S-400M Photoreceivers combine fast photodiodes with the proven and outstanding FEMTO HCA Current Amplifier technology. The HCA-S-400M is available with either a fast Si or InGaAs photodiode covering a spectral range from 320 to 1000 nm and 900 to 1700 nm, respectively. The amplifier transimpedance is 5 x 103 V/A resulting in a maximum conversion gain of 5 x 103 V/W at 1550 nm for the InGaAs model. The sophisticated DC coupled multi-stage amplifier design allows measurements from DC to a maximum bandwidth of 400 MHz corresponding to a minimum rise-time of 1 ns. Due to the low-noise design signals with an optical power in the micro-Watt range can be detected without the need for further averaging. Different models with free space or fiber optic input are available.
