Bandwidth and Frequency Response
The DHPCA-100 provides an optimum combination of gain and bandwidth. At the gain setting of 103 V/A it provides an extraordinary high 3 dB bandwidth of 200 MHz and even at the highest gain setting of 108 V/A the upper cut-off frequency is still an excellent 220 kHz. For those applications not requiring the full bandwidth the unit has a switchable 10 MHz and 1 MHz low pass filter to minimize broadband noise.

主要特點(diǎn)：
The Ultimate High Speed Current Amplifier
The DHPCA-100 variable gain transimpedance amplifier is the perfect choice for applications that require the conversion of small electrical currents into usable voltages at bandwidths up to 200 MHz. It is ideally suited for DC and AC measurements up to 200 MHz, time resolved measurements down to the ns-region and as the preamplifier for fast photodetector signals.
The DHPCA-100 offers many features including variable gain from 102 to 108 V/A, switchable AC/DC-coupling, adjustable offset for line correction, adjustable bias voltage for use with fast photodiodes, switchable 10 MHz and 1 MHz low pass filters and the capability of both manual and remote control. With its rugged and compact EMI shielded case the DHPCA-100 is the ideal universal high speed amplifier for a broad range of applications.
