Voltage Amplifier

Variable (gain 10 to 60dB), logarithmic (up to 80dB) and wideband (DC to 10, 200 or 500MHz) voltage amplifiers are available for a range of applications including universal low frequency amplification, industrial sensors, detector pre-amplification, oscilliscope and transient record pre-amplification, time resolved pulse and transient measurements, to LIDAR systems, signal compression and particle detection. Low frequency volatage amplifiers include control of gain settings and bandwidth by local switches directly on the amplifier.

100-200 MHz Wideband Series DHPVA

High-speed voltage amplifier with exceptional gain flatness for 10 μV to 100 mV

Description

The dependence of the gain setting with the bandwidth is minimised allowing rise/fall times to remain constant across the gain settings.

The bandwidth of simple amplifiers usually decreases with increasing gain. Therefore the rise time of pulses and fast signals will vary with the selected gain setting when measured with such amplifiers. This complicates exact and reliable time-resolved measurements. FEMTO has addressed this issue with a special design concept. As a result the DHPVA amplifier was born. The dependence of the gain setting with the bandwidth is minimised allowing rise/fall times to remain constant with ± 10 % maximum deviation across the full gain range.

Applications include Photomultiplier amplifier, Oscilloscope and Transient Recorder, Preamplifier signal booster for optical receivers and current amplifiers, Time-Resolved Pulse and Transient Measurements, Automated Measurement Systems, micro-channel plate (MCP) amplifier.
