WMA-300 High speed high voltage amplifier

The WMA-300 is a high voltage, wide bandwidth laboratory amplifier. Its high output voltage, current and wide bandwidth have been designed to serve the needs of a wide variety of high-tech experiments. The WMA-300 can be used for MEMS actuation, EO-modulators, PZT (piezo) positioners, ultrasonics, and many other applications. Two WMA-300 amplifiers and a WMA-IB-HS phase inverter - buffer can be used to double the output voltage.
