Coaxial Cable

JB series low loss stable amplitude flexible coaxial cable

Description

The JB series cables adopt a special structural design and advanced production technology, which enables the cables to have excellent electrical and mechanical performance indicators throughout the entire frequency range, and have a high cost performance ratio, making them the preferred low loss solution.

In terms of electrical performance, the signal transmission rate is as high as 76%, the temperature phase stability is less than 1000PPM, and it also has the advantages of low loss and high shielding efficiency. In terms of mechanical performance, low-density PT FE medium, silver plated flat wire weaving, and three-layer shielding are used; This structure is widely used in commercial aircraft, fighter jets, shipborne environments, and ground weapon systems. In terms of environmental use, high-quality outer sheath raw materials with environmental resistance are used to make it have characteristics such as wide temperature range, corrosion resistance, moisture and mold resistance, and flame retardancy.
