    Programmable attenuators are electronic devices that allow for digital control and precise adjustment of attenuation levels.

    They typically consist of a series of attenuators controlled by digital signals. Programmable attenuators can be controlled through RS-232 or USB interfaces, making it easy to integrate into larger systems. Compared to manual variable attenuators, they provide higher accuracy and repeatability, which is very useful in applications that require frequent adjustment or fine-tuning.

    Programmable attenuators have the following characteristics:

    1. Programmability: Digital or analog signals can be used to control attenuation, stepping, and switching between different attenuation levels and modes.
    2. Stability: It has a stable attenuation value and is usually not affected by temperature or other environmental conditions.
    3. High performance: in a wide range of engineering electromagnetic fields, it has good Electromagnetic compatibility, equality, low insertion loss and other excellent performances.
    4. Miniaturization: It can be integrated into small packages and has a very small size.

    Programmable attenuators are commonly used to simulate real-world signal attenuation scenarios and verify the performance of devices under different signal strength conditions. They are widely used in applications, wireless communication systems, and the design and testing of electronic circuits and components.

    Specifically, it includes:

    1. Communication system: Use it in adjusting wireless signal strength to avoid the impact of excessively strong signals on devices and systems.
    2. Instrument measurement: Use it for precise frequency adjustment and attenuation to meet testing requirements.
    3. Aerospace: In aviation, space technology, and navigation equipment, it is used for circuit calibration and attenuation control.
    4. Radio: It is used in the radio industry to regulate and attenuate signals.

    Qualwave supplies broad band and high dynamic range programmable-attenuators at frequencies up to 40GHz. The step can be 0.25dB and attenuation range can be 63.75dB or even more. Our programmable-attenuators are widely used in many areas.
