Flexible waveguide is a type of waveguide used for radio frequency and microwave signal transmission that is flexible and bendable. They are important in applications that require flexible wiring and installation, especially in systems where space is limited or where frequent adjustments are required.

Features:

Unlike hard waveguides made of hard structured metal tubes, soft waveguides are composed of folded tightly interlocked metal segments. Some soft waveguides are also structurally reinforced by sealing and welding the seams within the interlocking metal segments. Each joint of these interlocking segments can be slightly bent. Therefore, under the same structure, the longer the length of the soft waveguide, the greater its flexibility. Therefore, to some extent, it is relatively flexible compared to the application of hard waveguides and can solve various installation problems caused by misalignment.

The following are the main uses and applications of flexible waveguides:

1. Signal Transmission: Flexible waveguides are used to transmit radio frequency and microwave signals to ensure efficient transmission of signals between different devices and components.
Flexible Wiring: They allow for flexible wiring in complex and restricted spaces, adapting to various installation needs.
2. Vibration and Motion Compensation: Flexible waveguides can absorb and compensate for vibration and motion in the system, ensuring the stability and reliability of signal transmission.
3. Frequent Adjustments: In systems that require frequent adjustments and reconfigurations, flexible waveguides provide a convenient solution, reducing installation and maintenance complexity.
Flexible waveguide plays an important role in microwave systems due to its unique physical and electrical properties, and is widely used to solve installation problems, adjust positioning, adapt to environmental changes, and improve system reliability and stability.
