Low Loss Coaxial Cable – 034 Series

Home » Low loss Coaxial Cable 0.034-0.750 Series » Low Loss Coaxial Cable – 034 Series

034 Series Operating Up to 150 GHz

Our product range of low loss coaxial cables are designed to meet IW specifications for high performance across the electromagnetic spectrum to 150 GHz.

The 034 Series low loss coaxial cable is designed to deliver exceptional performance up to 150 GHz, making it an ideal choice for demanding applications up to millimeter wave frequencies.
0341 features a silver-plated copper center conductor, ensuring excellent electrical conductivity and minimal signal loss. The dielectric layer is composed of laminated PTFE, providing superior concentricity and stability across a wide temperature range.

For enhanced shielding and further reduction of signal loss, both the foil and braid layers are made of silver-plated copper, offering robust protection against external electromagnetic interference.

The outer jacket of the cable is FEP, measuring 0.057 inches (1.45 mm) in thickness, which not only provides mechanical durability but also chemical resistance, ensuring the cable’s integrity in various environmental conditions.

The combination of these high-quality materials and advanced construction techniques results in a reliable and efficient coaxial cable solution for critical communications, radar, and test and measurement applications.
