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

Main applications:

1. Power measurement: Bidirectional 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: Bidirectional couplers can be used to measure the amplitude and phase of microwave circuits, as well as for signal analysis and filtering.
3. Frequency converter: Bidirectional 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: Bidirectional couplers are often used as detectors, transmitters, and receiver control devices in digital communication.
