  • Precision Power Amplifier

    Dr. Hubert GmbH

    The main features of our power amplifiers are extreme broadband, low distortion and stability, above all. All amplifiers are operated and parameterized via a comfortable application software. The basic devices are mere voltage suppliers and provide 2 supply voltages and a USB interface.The letter "E" in the model name represents additional features: the amplifiers can optionally be operated as voltage amplifier or current amplifier; there are monitor outputs for voltage and current, and there are 3 symmetrical supply voltages available for optional selection.The amplifiers from the QE range provide "auto-commutating" voltage supply. In contrast to the E-models, 3 bipolar supply voltages are individually switched either automatically or manually.The QE-models provide highest sink outputs and are thus also suitable for operation as active load.For detailed information on HUBERT amplifier technology please see our White Paper No.1: HUBERT power amplifiers.

  • High-Frequency Amplifier

    Dr. Hubert GmbH

    The RF broadband power amplifiers from the A1020 product range are robust class -A/-AB amplifiers for EMC testing and general laboratory applications. Stability under all load conditions occurring in practice, a wide frequency range, low degree of distortion, and a fair purchase price are the main characteristics of these amplifiers. Optimum cooling is ensured through implementation of a high-power heat sink with temperature-controlled fans. Sophisticated protection equipment ensures hardware integrity, even at extreme load conditions.

  • Isolation Amplifier

    Dr. Hubert GmbH

    Isolation amplifiers are indispensable components for signal conditioning. There are several reasons that make galvanic potential isolation necessary. Examples for this are personal protection, on the one hand, as required in medical engineering to ensure contact of persons with life-threatening voltages. On the other hand, different safety aspects, such as protection of IT systems may require the use of an isolation amplifiers. If ground loops need to be separated or if a small differential voltage with a high common-mode level must be determined, the isolation amplifier is the device of your choice.
