Voltage Amplifier Modules cover bandwidth from DC-500 MHz.
Press Release Summary:
Series HVA Amplifier Modules feature gain ranges from 20-60 dB and low input noise of 0.9 nV/SQR(Hz) minimum. Four models in series have 2 gain settings. Small size of EMI shielded package allows use close to signal source, eliminating noise pick-up from long signal cables. Amplifiers are available with 50 ohm bipolar input for low impedance sources or 1 M ohm FET input for high impedance sources. Offset can be adjusted with integrated trimpot.

FEMTO Introduces 5 Low Noise Voltage Amplifier Modules
FEMTO has just introduced the new HVA series of Low Noise Voltage Amplifier Modules. The five new models cover a bandwidth range from DC to 500 MHz. The amplifiers have a very low input noise [0.9 nV/SQR(Hz) minimum and are ideally suited for applications requiring high gain with ultra low-noise performance. The gain ranges from 20 to 60 dB, depending on the amplifier selected. Four HVA amplifiers have 2 gain settings. The small size of the rugged EMI shielded package allows them to be used close to the signal source to prevent further noise pick-up from long signal cables. The amplifiers are available with either (1) a 50 Ohm bipolar input for low impedence sources or (2) or a 1 MOhm FET input for high impedance sources. The offset can be adjusted with the integrated trimpot.
Typical applications (1) include time-resolved pulse and transient measurements, (2) amplifier for oscilloscopes, (3) transient-recorders, (4) photomultipliers, (5) microchannel-plates and (6) amplification of digital signals with no baseline shift of digital code.
The new HVA amplifiers complement the well-known DHPVA-series of voltage amplifiers which offer expanded gain settings, signal filter functions and a remote control interface.
FEMTO manufactures a line of high quality specialty amplifiers for signal recovery and processing. These products include Low Noise Current Amplifiers, High and Low Frequency Voltage Amplifiers, Photoreceivers, High Speed GHz Amplifiers and Lock-In Amplifiers.
