    Dual Directional Coupler is a widely used microwave device mainly used for power measurement and signal analysis of electromagnetic signals. Its main feature is that the energy between the main and auxiliary circuits can be collected and analyzed without interfering with the main circuit.

    Other features are as follows:

    1. Bidirectional transmission: Microwave dual directional couplers can receive and allocate signals from multiple directions.
    2. Low insertion loss: Microwave dual directional couplers can minimize their impact on the signal while separating it, maintaining low insertion loss.
    3. High isolation: Microwave dual directional couplers can provide high isolation between two transmission channels to prevent bandwidth mixing and signal interference.
    4. Broadband: Microwave dual directional couplers can operate over a wide frequency range, making them suitable for various applications.
    5. Consistency: Microwave dual directional couplers can maintain common design and specifications in different environments, enabling efficient operation in multiple systems.

    Main applications of coaial dual directional couplers:

    1. Power measurement: Power Amplifiers dual directional couplers can measure power balance and matching in microwave circuits, which is very helpful for locating fault points and checking device performance indicators.
    2. Signal analysis: Bi dual directional couplers can be used to measure the amplitude and phase of microwave circuits, as well as for signal analysis and filtering.
    3. Frequency converter: RF dual directional couplers can also form variable frequency circuits and filters, and are often used in various fields such as electronic measurement equipment, radar equipment, satellite communication equipment, and radio communication systems.
    4. Digital communication: Millimeter wave dual directional couplers are often used as detectors, transmitters, and receiver control devices in digital communication.

    Qualwave supplies broadband high power dual directional couplers in a wide range from 4kHz to 67GHz. The radio frequency dual directional couplers are widely used in many applications.
