Electro Optical Components, Inc. 200 MHz High Speed Photoreceivers HCA-S-200M

The series HCA-S-200M Photoreceivers combine fast photodiodes with the proven and outstanding FEMTO HCA Current Amplifier technology. The HCA-S-200M is available with either a fast large area Si or InGaAs photodiode covering a spectral range from 320 to 1000 nm and 900 to 1650 nm, respectively. The amplifier transimpedance is 2 x 104 V/A resulting in a maximum conversion gain of 2 x 104 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 200 MHz corresponding to a minimum rise-time of 1.8 ns. With a NEP as low as 6 pW/√Hz signals with an optical power in the micro-Watt range can be detected without the need for further averaging.
