The Falco Systems WMA-300 is a high voltage, high
speed laboratory amplifier for demanding applications. Its
wide bandwidth and large voltage range make it an
excellent choice for use with MEMS devices, EOmodulators, PZT (piezo) positioning systems, beam
steering components, ultrasonics, and many more.
The amplifiers’ full-power frequency response is
essentially flat up to 2MHz. To ensure proper HF
operation, the input has an impedance of 50 Ohms. It
contains an extensive over-voltage protection for the daily
use and abuse in the laboratory.

In other high-speed negative feedback amplifiers, instability
under capacitive loading conditions is a common problem.
This often results in unwanted overshoot voltages, and - in
extreme cases - oscillations. In the WMA-300, this problem
has been rigorously solved by a clever dual feedback
system. No significant overshoot occurs at any capacitive
load.
Output overload or short-circuit conditions are also no
problem, due to the extremely fast output current limiting
circuit that has been employed.
