High-speed digital system design staff using specially designed Gore custom coaxial cable to meet the most challenging assembly and electrical requirements. Gore using expanded polytetrafluoroethylene (ePTFE) material to form low dielectric constant (1.3) insulation, durable, thin cable can be used as a thin, stable and reliable connection between both is the best to meet specific system requirements good program.
Advantages
• higher density assembly
• a higher fidelity signal
• Low capacitance
• the minimum propagation delay (about 1.2 ns / ft)
Form Factor
In addition to coaxial form, the Gore company to make the cable impedance for differential signals, but also a key signal for the application of the production strip coaxial cable and ordinary ribbon cable, providing the components are fully tested. If the standard connector is not suitable, Gore will design custom components to meet customer specific requirements.
Impedance control to improve the signal fidelity
Correct impedance matching can minimize the reflection of the terminal to improve signal fidelity, on the finished cable assemblies, precision is essential. In order to ensure proper impedance matching, Gore has made all the coaxial cable assemblies precision engineering components, in the production process for a large number of quality checks.
Maintain the fidelity of low-loss
Gore precision coaxial low loss characteristics of the signal components from the cutting-edge design work, attention to detail of the production process and excellent dielectric properties of the finished product. Finished cable can maintain the waveform, making the longer distance signal transmission, processing weak signals without distortion or attenuation. For example, in LSI (large scale integrated circuit) applications, using low-loss cable assembly line driver does not need amplification.
Small signal delay
Gore coaxial cable assemblies minimum signal delay, about 1.15 ns / ft, which greatly increased the propagation velocity and optimize the performance of mutual connections in urgent applications can shorten the wait state, such as computer peripherals and synchronization of switching systems the clock line. Failure to achieve precise control of speed may not improve performance. Gore's cables and components to ensure that the processing time delay difference between the minimum line.
Small capacitive load
Gore expanded polytetrafluoroethylene (ePTFE) dielectric capacitance of about the same resistance than most of the capacitance of insulating material is 20%, which greatly reduces the load on the system output drivers, but also to maintain the integrity of the signal waveform, the characteristics of low signal intensity in the probe involving the application particularly useful.
Enhanced anti-jamming performance
As requirements continue to improve the speed, the designer must use differential signals to improve the critical path of the noise margin. Gore to understand the unique requirements of different signals, for the development of symmetrical cable and connector system; we can test and play to help determine the real difference these interconnect performance.
High signal quality
Gore's expanded PTFE dielectric material creating a small controlled impedance cables for best performance. Our production process to achieve a smaller conductor size, minimum to AWG 42 (0.0025 '). Al Gore, the dielectric constant of dielectric material loss tangent is less than 1.3 and less than 0.0002, PTFE can keep the heat and chemical resistance, easy installation and assembly of the connector to withstand the process of high temperature and high pressure.
Cable Accessories
Gore offers a variety of standard number of precision coaxial cable, part of which is shown below. Can also be customized according to customer requests for the cable configuration.
