    Attenuator is a control component whose main function is to reduce the signal strength passing through the attenuator. In practical applications, RF attenuators may operate in different temperature environments, giving rise to lcryogenic fixed attenuators. We have designed attenuators for low temperature environments (-269~+125 degrees Celsius) by selecting suitable raw materials and improving the level of technology.

    Cryogenic fixed attenuators have good thermal conductivity and high stability at extremely low temperatures. On the one hand, microwave attenuator can be used as signal amplitude attenuators, and on the other hand, millimeter wave attenuator can be used as heat sinks for cold transfer. Mm wave attenuator can be used in fields such as deep space exploration, radio astronomy, quantum computing, and wireless communication, especially in low-temperature physics experiments and superconductor research.

    Purpose:

    1. Signal Attenuation: Cryogenic fixed attenuators are used to accurately attenuate the strength of RF and microwave signals in extremely low temperature environments. This is important for protecting sensitive receiving equipment and controlling signal levels.
    2. Noise Control: By attenuating the signal, the noise and interference in the system can be reduced, thereby improving the signal-to-noise ratio (SNR) of the signal.
    3. Matching Impedance: Cryogenic fixed attenuators can be used to match the impedance of the system, thereby reducing reflections and standing waves and improving system performance.

    Application:

    1. Cryogenic physics experiment: In low-temperature physics experiments, cryogenic fixed attenuators are used to control and adjust signal intensity. These experiments often involve the study of superconductors, quantum computing and other low-temperature phenomena.
    2. Superconductor Research: In superconductor research, cryogenic fixed attenuators are used to condition and control radio frequency and microwave signals to study the properties and behavior of superconductors.
    3. Quantum Computing: In quantum computing systems, cryogenic fixed attenuator are used to regulate signal strength and interactions between quantum bits (qubits). This is crucial for achieving high-precision quantum computing operations.
    4. Astronomy and Radio Telescopes: In astronomy and radio telescope systems, RF attenuators are used to adjust the strength of received celestial signals. This helps improve the quality and accuracy of observational data.
    5. Cryogenic Electronic Equipment: In low-temperature electronic equipment, microwave attenuator are used to control and adjust signal strength to ensure normal operation and high performance of the equipment.
    In short, cryogenic fixed attenuators are widely used in many fields such as cryogenic physics experiments, superconductor research, quantum computing, astronomy, and cryogenic electronic equipment. They improve system performance and reliability by precisely controlling signal strength and reducing noise.

    Qualwave supplies various high precision cryogenic fixed attenuators cover the frequency range DC~40GHz. The average power is 2 watts. The attenuators are used in many applications where reduction of power is needed.
