High voltage amplifiers




High Voltage Amplifier Technology

Trek high-voltage power amplifiers use a closed-loop amplifier system with exceptional DC stability and excellent wideband performance. The units are solid-state and fully protected against arc-over and operation into short circuits. Power amplifiers employ a unique four-quadrant class AB high-voltage output stage constructed using MOS power transistor devices in a proprietary multidevice cascode configuration. This cascode connection provides tight voltage and power sharing across all devices in the cascode array to yield exceptional MTBF reliability performance.

As the stability of the closed-loop amplifier system is dependent upon the feedback voltage divider stability over time, temperature, and humidity, Trek employs an advanced thin film resistance technology in its feedback dividers. The signal from the feedback divider, being a precision divided representation of the amplifier output signal, is used to provide a low-level voltage monitor signal and to complete the feedback loop by comparing the divider output against the amplifier input signal in a high-gain integrating stage. The output of the integrating stage is used to drive optical couplers connected to the output stage cascode connected MOS device arrays, thus closing the feedback loop.To generate the high voltage required by the output stages, high-voltage, high-frequency switching type power supplies are typically used.

High-Voltage Amplifier Characteristics

  • Designed for wide bandwidth, high slew rate and low noise
