    Voltage controlled attenuators are integrated circuit devices that can control the degree of attenuation of their output signals through external input voltage signals. Its main characteristics and applications are as follows:

    Features:

    1. Adjustability: Voltage controlled attenuators adjusts the attenuation degree of its output signal through external input voltage signals, enabling precise adjustment and control.
    2. High linearity: There is a high linear relationship between input voltage and output attenuation, making Voltage controlled attenuators highly accurate and stable in practical applications.
    3. Wide bandwidth: Voltage controlled attenuators has good linear response in the frequency range, so it can be applied to a wide range of frequency signals.
    4. Low noise: Due to the use of low noise components in the internal circuit design of Voltage controlled attenuators, Voltage controlled attenuators exhibits very low noise indicators during operation.
    5. Integratability: Voltage controlled attenuators can be integrated into other circuits, resulting in a smaller volume and higher integration of the entire system.

    Application:

    1. Communication system: Voltage controlled attenuators can be used to adjust the signal strength in the communication system, achieving signal regulation and control during data transmission and reception.
    2. Audio control: Voltage controlled attenuators can serve as an audio control unit in the audio system to control the attenuation of audio signals.
    3. Instrument measurement: Voltage controlled attenuators can be used as a control component in instrument measurement to accurately control and adjust signals, achieving instrument accuracy and stability.
    4. Sound processing: Voltage controlled attenuators can be applied to sound processing, such as synthesizers, distortors, compressors, etc.

    Qualwave supplies broad band and high dynamic range voltage controlled attenuators at frequencies up to 40GHz. Our voltage controlled attenuators are widely used in many areas.
