UAV flight control and image transmission signal transmission analysis: why choose extremely thin coaxial cable束

In the drone system, the signal link between the flight control (flight controller) and the image transmission module is a key factor affecting flight stability and image quality. In order to achieve high-speed, low-latency, and anti-interference signal transmission in lightweight bodies, ultra-fine coaxial cables have gradually become a widely adopted solution in the industry.

Signal integrity to meet high-speed transmission requirements

The data link between the flight control and image transmission contains high-definition video signals and various control commands, which places extremely high requirements on the frequency characteristics and anti-interference performance of the cables. Extremely thin coaxial bundles have good impedance control and shielding structures, which can effectively reduce electromagnetic interference, maintain the stability and integrity of high-speed signals, and lower the image transmission delay, resulting in clearer images.

Two, lightweight and flexible characteristics suitable for the internal space of drones

The space inside the drone's body is limited and extremely sensitive to weight. The micro coaxial cable has a small outer diameter and strong flexibility, allowing for compact wiring within the body. Its small bending radius is suitable for dynamic motion structures between the gimbal, camera module, and flight control board, significantly enhancing the freedom of wiring while ensuring the whole machine is lightweight.

Three, stability and customization ability in response to the flying environment

Drones may encounter environmental changes such as vibration, temperature difference, and high-altitude humidity during flight. The extremely thin coaxial cable束 has excellent reliability, ensuring long-term stable operation. In addition, regardless of whether the specifications of the flight control and image transmission interfaces are consistent, the cable束 can be adapted and customized to improve system compatibility and reduce risks such as poor welding and poor contact.

In the high-speed interconnection between flight control and downlink transmission, extremely thin coaxial cable bundles offer high-frequency performance, lightweight design, and durable reliability, making them the mainstream solution widely used in unmanned aerial vehicle signal transmission. Their advantages in wiring flexibility, signal integrity, and system compatibility make them an important foundation for constructing a stable downlink transmission system.
