Features and Benefits

  • Custom precision: manufactured to exact specified lengths and bent to precise radii and angles.
  • Superior electrical performance: ultra-low end-to-end loss, excellent VSWR, unmatched shielding, and optional phase and amplitude matching.
  • Reduced installation time and cost: arrive as ready-to-install components, eliminating in-house preparation.
  • Enhanced reliability and repeatability: robust construction resistant to vibration, shock, and environmental stresses.
  • Design flexibility: wide variety of cable diameters, plating options, and connector types (SMA, SMP, 2.92mm, 1.85mm, etc.).

Impedance
50 Ohms (standard).
Frequency Range
DC up to 100 GHz and beyond, depending on cable/connector.
Insertion Loss
Minimized total loss for the assembly.
VSWR
1.25:1 or better, even at higher frequencies, for max power transfer and minimal return loss.
Shielding Effectiveness
Typically >100 dB for signal isolation.
Phase Stability
Excellent with temperature, minimal shifts when formed.
Power Handling
High, due to efficient thermal dissipation.

Cable Types
Standard semi-rigid coaxial cables (.020" to .250" OD).
Outer Conductor Material
Copper or Aluminum; bare copper, tin, or silver plating.
Dielectric Material
PTFE (solid, low-density) for optimized performance.
Inner Conductor Material
Silver-plated copper-clad steel or bare copper.
Connectors
