    Fixed attenuator is an electronic component whose function is to reduce the power of the radio frequency signal in the transmission process, so that the signal can be transmitted, distributed and processed in different circuits.

    The application scenarios of fixed attenuators are very wide, including:

    1. Communication system: Fixed attenuators are often used to adjust the signal strength between the terminal device and the main device to ensure the communication quality between the devices.
    2. Network distribution system: Fixed attenuator can help adjust signal strength to adapt to different transmission media, such as cable, optical fiber, etc., to ensure stable transmission of information in the network.
    3. Measurement and detection systems: Fixed attenuators can be used to calibrate signal power in test and detection systems to ensure the accuracy and accuracy of test data.
    4. Television and radio systems: Fixed attenuators can help adjust signal strength and match jammers to improve the quality and stability of television and radio signals. In short, the fixed attenuator is an important component that can adjust and match the signal power in the process of radio frequency signal transmission. It can be used for signal testing, signal matching, signal attenuation, and has a wide range of applications.

    The fixed attenuator has a fixed attenuation value, and the value of the impedance cannot be adjusted at will. Its main indicators include attenuation value, operating frequency range, power, VSWR, attenuation accuracy, etc. These indicators determine the application range and performance of the fixed attenuator.

    Qualwave supplies various high precision and high power coaxial fixed attenuators cover the frequency range DC~67GHz. The average power handling is up to 2K watts. The attenuators are used in many applications where reduction of power is needed.
