Standalone 4-channel wideband amplifier

19 April 2006 Test & Measurement

Tabor Electronics has added the Model 9400 to its wideband power amplifier line. Designed as a general purpose, standalone unit, 9400 is a 4-channel wideband high voltage amplifier in a small, space-and cost-saving package featuring superior bandwidth and signal integrity.

The 9400 has two modes of operation. The first, 'Normal', amplifies each signal separately and outputs bipolar signals with a gain of x50. The second mode, 'Unipolar', applies the signal to a single input, rectified, amplified and output through two separate outputs. Using this mode, the amplifier is converted to a two-input, four-output system, specifically designed to operate the up/down and right/left actuators of a typical MEMS micro engine, as well as for other applications requiring the precise conversion of bipolar to unipolar signals.

The 9400 wideband amplifier also has the following features:

* Four independent channels.

* -200 to +200 V (400 Vp-p) with up to 50 mA output current.

* Full power bandwidth from DC to 500 kHz.

* Precise signal amplification for multiple applications.

* Compatibility with all Tabor arbitrary waveform generators.

* Protective latch for instant disconnect of high voltage power from output terminals.

* Monitor Outputs for each channel dividing the main output signal by 100.

* Special 'Unipolar' mode for MEMS engine drivers.
