Professional Industry Advantages
-
Copper Clad Steel Strength: By utilizing a high-strength Silver-plated Copper Clad Steel (SPCCS) inner conductor, this cable offers superior tensile strength and durability compared to soft copper alternatives, ensuring long-term phase stability in high-vibration aerospace or military environments.
-
100 Percent Shielding Effectiveness: The seamless bare copper tube outer conductor provides an absolute electromagnetic seal. This ensures zero signal leakage and total immunity to external interference, which is a critical requirement for high-density microwave integrated circuits.
-
Ultra-Low Loss Performance: Specifically optimized for the 0 to 20 Gigahertz frequency spectrum. Its high-purity PTFE insulation maintains an exceptionally low dielectric constant, resulting in minimal signal attenuation even at higher microwave bands.
-
Superior Power Handling Capability: Designed to carry high power loads (up to 162 Watts at 1 GHz) within a compact 2.20 mm profile, making it a powerful solution for transmitter output stages and high-gain antenna systems.
-
Shape Retention & Mechanical Stability: The semi-rigid nature of the annealed copper tube allows the cable to be precision-bent into complex three-dimensional shapes during assembly. Once formed, it maintains its geometry, providing consistent electrical paths without the signal fluctuations common in flexible cables.
