Precision Coaxial Cable

Designers of high-speed digital systems use GORE custom-designed coaxial cables to meet their most challenging packaging and electrical requirements. GORE expanded PTFE material provides a low dielectric constant (1.3) insulation system, durable enough to apply in thin walls over small conductors. The result is a reliable interconnect, optimized to meet specific system needs.

Benefits

• Higher packaging density
• Higher signal fidelity
• Lower capacitance
• Lowest propagation delay (about 1.2 ns/ft)
  

Form factors

In addition to coaxial forms, Gore can build controlled impedance pairs for differential signals. We can also manufacture our coaxial cables and pairs in ribbon form for critical signal applications. Fully tested assemblies are available. When standard connectors will not work, we can design and build custom assemblies to meet customer specifications.

Impedance control improves signal fidelity

Proper impedance matching minimizes reflections at terminations, enhances signal fidelity, and is critical for precise performance in finished cable assemblies. To ensure proper impedance matching, we build all GORE coaxial assemblies as precision-engineered components and perform numerous quality checks during manufacturing.

Low loss preserves fidelity

The low signal-loss characteristics of GORE precision coaxial assemblies stem from sophisticated design engineering, meticulous manufacturing procedures, and the superb dielectric properties of the finished product. Finished cables preserve waveforms, allow longer signal lengths, and handle weaker signals without distortion or degradation. In LSI applications, for example, low-loss cable assemblies can eliminate the need for amplifying line drivers.

Lower signal delay

GORE coaxial assemblies exhibit minimal signal delay, approximately 1.15 ns/ft. Low signal delay significantly increases rep rates, optimizes interconnect performance, and reduces wait states in such critical timing applications as clock lines in computer peripherals and synchronized switching systems. Higher speed alone may not improve performance unless it can be precisely controlled. GORE cable and assembly processing assures minimum delay skew between lines.

Less capacitance loading

The capacitance of GORE ePTFE dielectric material is approximately 20 percent less than that of most insulating materials at the same impedance. This greatly minimizes loading on system output drivers. It also preserves signal waveform integrity, a particularly useful feature in probe applications that involve very low signal strengths.

Increased noise immunity

Continually increasing system speeds have led designers to use differential signals to improve noise margins for critical lines. Gore understands the unique requirements of differential signals and has developed balanced cables and connector systems for them. We can help specify methods for testing and characterizing these interconnects for true differential performance.

High signal quality

GORE expanded PTFE dielectric provides optimum performance in miniaturized, controlled impedance cables. Our manufacturing processes allow miniaturization with conductor sizes as small as AWG 42 (.0025"). With its dielectric constant of less than 1.3 and loss tangent of less than .0002, GORE dielectric material maintains the heat and chemical-resistant properties of PTFE and easily withstands the temperature and pressure extremes that occur during installation and connector attachment.
