Coaxial cable JA146 series: small diameter, 110GHz operating frequency
2024-08-05 15:27:20
Coaxial cable is a kind of wire and signal transmission line, which is generally made of four layers of materials: the innermost is a conductive copper wire, and the outer layer of the wire is surrounded by a layer of plastic, which serves as an insulator and dielectric; the outer layer of the insulator is a thin mesh conductor, generally copper or alloy; and the outer layer of the conductor is the outermost insulating material as the outer sheath. As shown in Figure 1. Coaxial cable can be used for the transmission of analog and digital signals and is suitable for a variety of applications.
The company's JA series coaxial cables adopt special coaxial design and advanced production technology, which makes the cables have excellent electrical and mechanical performance indicators in the full frequency range; among them, the JA146 cable is currently the smallest diameter in this series, with an outer diameter of 1.46mm, which can replace the world-renowned RF cable CXN3657. The standard FEP sheath color is mysterious light violet, the operating frequency band is DC-110GHz, the characteristic impedance is 50Ω, the signal transmission rate is 80%, 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 bendability and superior mechanical phase stability; in terms of environmental use, the operating temperature is -55℃~165℃, and the purchase of high-quality environmentally resistant raw materials makes it have a wide temperature range, corrosion resistance, moisture and mildew resistance, and flame retardancy.
JA146 coaxial cable is widely used in phased array radars, missile equipment, vehicle-mounted equipment, ship-borne missile-borne microwave module interconnection, shipboard communication equipment, avionics, electronic countermeasures, military, commercial base stations, small and complex installation spaces, military, commercial antennas, and any demanding interconnection occasions that require low loss and relative stability.
