產品名稱：DHPCA-100可變增益電流放大器
產品型號：DHPCA-100
產品品牌：德國FEMTO
產品簡介：
Bandwidth and Frequency Response
The DHPCA-100 provides an optimum combination of gainand bandwidth. At the gain setting of 103 V/A it provides an extraordinary high3 dB bandwidth of 200 MHz and even at the highest gain setting of 108 V/A theupper cut-off frequency is still an excellent 220 kHz. For those applicationsnot requiring the full bandwidth the unit has a switchable 10 MHz and 1 MHz lowp filter to minimize broadband noise.
技術參數：
Transimpedance Gain from 102 to 108 V/A
Bandwidth up to 200 MHz
Rise Time down to 1.8 ns
Internal Signal Filters
Adjustable Bias Voltage
Manual and Remote Control
主要特點：
The Ultimate High Speed Current Amplifier
The DHPCA-100 variable gain transimpedance amplifier isthe perfect choice for applications that require the conversion of allelectrical currents into usable voltages at bandwidths up to 200 MHz. It isideally suited for DC and AC measurements up to 200 MHz, time resolvedmeasurements down to the ns-region and as the preamplifier for fastphotodetector signals.
The DHPCA-100 offers many features including variablegain from 102 to 108 V/A, switchable AC/DC-coupling, adjustable offset forbaseline correction, adjustable bias voltage for use with fast photodiodes,switchable 10 MHz and 1 MHz low p filters and the capability of both manualand remote control. With its rugged and compact EMI shielded case the DHPCA-100is the ideal universal high speed amplifier for a broad range ofapplications.
