技术问答

In various fields such as radio frequency communication, microwave technology, optical communication, and semiconductor testing, semi-rigid coaxial cables have attracted much attention due to their unique performance and wide range of applications. The development of semi-rigid coaxial cables can be traced back to the early demand for RF communication. With the continuous advancement of wireless communication technology, higher requirements have been put forward for cables' electrical performance, mechanical performance, and environmental adaptability.

Semi rigid cables, with their unique combination of rigidity and flexibility, are gradually occupying a place in high-end communication systems. In recent years, with the widespread application of technologies such as distributed antenna systems (DAS) and phased array antennas, the market demand for semi-rigid 141 cables has continued to grow due to their support for high-frequency signal transmission and phase stability. Among them, JD141 low loss semi-rigid fixed coaxial cable, as an important member of the semi-rigid cable series, plays an irreplaceable role in multiple key systems due to its excellent electrical performance, phase stability, and stability in low-temperature environments.

04.01.AA00140 JD141

Electrical characteristics:

● Frequency range: DC to 26.5GHz, JD086 and JD116 models can reach higher frequencies.

● Impedance: 50 Ω, compliant with most RF system standards.

● Propagation rate: 81%, ensuring efficient signal transmission.

● Dielectric constant: 1.52, affecting electrical signal transmission and electrical characteristics.

● Distributed capacitance: 79.4pF/m, which is of great significance for performance optimization.

● Signal delay: 4.11ns/m, which is particularly critical for applications that require precise control of signal phase.

● Dielectric voltage: 800V, DC, indicating that the cable still operates reliably in high-voltage environments.

● Shielding efficiency: ≤ 110dB, providing excellent electromagnetic shielding performance.

Environmental and mechanical characteristics:
● Working temperature range: minimum -55℃, maximum+265℃, with strong adaptability to temperature changes.

● Bending radius: The static bending radius is 14mm, indicating that the cable has a certain degree of flexibility when bent, but attention should be paid to avoiding excessive bending to avoid damage.

● Weight: 45g/m, relatively light, easy to install and deploy.

● Flame retardancy: Compliant with RoHS standards, environmentally friendly, and safe.
