3D-FB Coaxial Cable

The 3D-FB technology represents a high-tier manufacturing process for coaxial cable dielectrics. Its primary benefits are lower signal loss, superior stability, and enhanced reliability, making it the preferred choice for demanding RF applications where performance and longevity can not be compromised.

1.Advanced Foamed Dielectric(3D-FB Structure):
a.The dielectric is made of polyethylene that is physically foamed with an inert gas
(like nitrogen).
b.This creates a closed-cell structure with a smooth, solid "skin" on the inside an outside,
And a rigid, uniformly foamed "bone" structure in the middle. This is the "Skin-Bone"
analogy.
2.High Porosity /Low Density:
The foaming process fills the dielectric with countless tiny air cells. Since air is an excellent insulator, this significantly reduces the overall density of the dielectric material without sacrificing structural integrity.
3.Stable Mechanical Construction:
The solid "skin" layers prevent the foam from collapsing or deforming easily during bending or crushing, ensuring long-term stability of the electrical characteristics.
4.Precise and Consistent Dimensions:
The manufacturing process for 3D-FB dielectric allows for extremely tight tolerances on the diameter and concentricity( the central conductor being perfectly centered). This consistency is critical for maintaining a stable impedance (e.g.,50 or 75ohms).

Due to these advantages, 3D-FB coaxial cables are used in high-performance, professional, and critical applications:

· Cellular Infrastructure: Feeder cables for macro and micro cell sites (e.g., Andrew/CommScope HELIAX, RFS cables).

· Broadcast TV & Radio: Connecting high-power transmitters to antennas.

· Land Mobile Radio (LMR): Public safety and commercial two-way radio systems.

· Microwave Links: Backhaul connections between sites.

· Military and Aerospace: Where reliability and phase stability are paramount.

*The attenuation is typical value, Maximum value shall be 105% of the nominal attenuation value.
