    • 一、FEATURES

      Transimpedance amplifier with gain from 10^2 to 10^8 V/A

      Bandwidth up to 200 MHz

      Rise time down to 1.8 ns

      Internal signal filters

      Adjustable bias voltage

      Manual and remote control

      二、THE ULTIMATE HIGH SPEED TRANSIMPEDANCE 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 10^2 to 10^8 V/A, switchable AC/DC-coupling, adjustable offset for baseline 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.

      三、BANDWIDTH AND FREQUENCY RESPONSE

      The DHPCA-100 provides an optimum combination of gain and bandwidth. At the gain setting of 10^3 V/A it provides an extraordinary high 3 dB bandwidth of 200 MHz and even at the highest gain setting of 10^8 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.

      四、APPLICATIONS

      Current to voltage converter for current measurement

      Photodetector amplifier

      Fast ionization detection

      Spectroscopy

      Preamplifier for oscilloscopes, A/D converters and RF lock-in amplifiers
