Coaxial Cable

Ultra-low loss stable phase flexible coaxial cable

Description

JA series cable adopts special coaxial design and advanced production process, so that the cable has excellent electrical and mechanical performance indicators in the full range of frequency bands.

In terms of electrical performance, the signal transmission rate is as high as 83%, the temperature phase stability is less than 550PPM, and it also has the advantages of low loss, high shielding efficiency, and high power. In terms of mechanical properties, low density insulation and copper tape wrapping make the cable have better bending and superior mechanical phase stability. In terms of environmental use, the raw materials with high environmental resistance performance are used to make it have the characteristics of wide temperature range, corrosion resistance, moisture, mildew and flame retardant.
