75-ohm high-bandwidth video coax: For digital video, cameras, displays and precision measurement links through 12 GHz.
50-ohm instrumentation coax: For timing, sensing, instrumentation and equipment-module links through 3 GHz.
Micro-coax construction: Reduces diameter and mass inside equipment, multi-coax connectors and dense assemblies.
Center conductor: Solid or stranded geometry selected for attenuation, flexibility and termination.
Dielectric: Concentric low-loss insulation establishes impedance and electrical length.
Outer conductor: Foil, braid or composite return path provides shielding and mechanical stability.
Jacket: Protects the coax while controlling diameter, friction and bend behavior.
Connector transition: Termination geometry is treated as part of the impedance-controlled path.
Impedance: 50 Ω, 75 Ω or project-defined target
Frequency/data content: Highest frequency, edge rate and link budget
Length: Assembly length, tolerance and connector transitions
Size and flex: Outer diameter, bend radius and motion
Shielding: Coverage, leakage target and grounding
Interface: Cable-end connector, board transition or bundled harness
