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.
