The WMA-300 HV amplifier:
general description
The Falco Systems WMA-300 is a high
speed,
high-voltage
linear
amplifier for demanding applications. Its
wide bandwidth and large voltage range
High Voltage Amplifier DC – 5MHz
USER MANUAL
make it an excellent choice for use with
MEMS devices, EO-modulators, piezo
positioning
ultrasonics, dielectric studies, and many
others.
Through the extensive use of computer
modelling
concepts, this amplifier can be used in
many applications, including those where
conventional amplifiers are difficult to
apply. It is designed to be absolutely stable
and free of spurious signals with any
capacitive load.
The amplification is 50x (fixed). With a
laboratory
range of –150V to +150V, a large signal
bandwidth of 5MHz @ -3dB and a typical
slew rate of 2000V/μs, this amplifier will
systems,
beam
