Product Description

DHPCA-100 FEMTO PS-15-25-L current preamplifier module
The DHPCA-100 variable gain amplifier is the best choice for applications requiring conversion from small current to usable voltage at bandwidth values up to 200MHZ. It is well suited for DC and AC measurements up to 200 MH, time resolution measurements into the ns region and rapid photodetector signals as a preamplifier

Bandwidth and frequency response
The DHPCA-100 provides the best combination of gain and bandwidth. It has A bandwidth of up to 3dB at 103V/A gain adjustment, 200MHz, and a 108V/A cutoff frequency of 220kHz at the maximum gain adjustment. For those application components that do not require full bandwidth there is a 10MHz to 1MHz switchable low-pass filter to minimize broadband noise.
