1、GORETM HIGH FREQUENCY COAXIAL CABLECreative Technologies WorldwideInternational: +86/21 6247 1999 phone+86/21 6247 9199 W. L. Gore & AssociatesIntroductionW. L. Gore & Associates, Inc., a company with more than 25 years experience providing high performance microwave cable assemblies, is pleased to
2、 offer a complimentary line of bulk coaxial products. The cable designs detailed below are based on the same quality materials and process found in the Gores microwave assembly business, but are available as a bulk product to allow customers greater flexibility for connector termination.Size-for-siz
3、e Gore microwave coaxial cable provides the lowest insertion loss on the market today. This is accomplished through a unique cable design that exploits the low dielectric constant, low loss tangent, and conforming nature of the expanded polytetrafluoroethylene (ePTFE) dielectric. The basic cable des
4、ign is detailed in FIG 1. The conforming nature of the ePTFE dielectric allows for the use of an electrical shield with 100% coverage consisting of a helically wrapped, multi-layer, silver-plated copper foil (flatwire).The scope of the product line will cover standard constructions starting with “Ty
5、pe 89”, an 0.085” diameter cable designed for high-density, high routability applications, and extending to “Type 320”, a 0.320” diameter cable designed for optimized insertion loss performance through 18 GHz.PerformanceAll of the bulk cables constructions are designed and manufac-tured with broadba
6、nd performance specified where the cable is expected to operate virtually free of moding and narrow band VSWR and insertion loss anomalies. All cable is inspected and tested against Gores standard insertion loss and VSWR specification. A table is provided to describe the attenuation performance for
7、the standard construction.Vertical integrationGore is unique as a high frequency cable manufacturer because of the vertical integration for the critical materials that control electrical performance. Gore is recognized as the worlds premier producer of expanded PTFE tape dielectrics. Our high freque
8、ncy bulk cable product family fully leverages this expertise and GOREs high standards for performance and quality also extend to the in-house conductor and flatwire shield production. By controlling all of the materials in the cables signal path, Gore can deliver the highest perfor- mance with the l
9、east variability in the industry. ConnectorsGore offers a broad range of microwave connectors to compliment the bulk product line, which will allow the end user to create high performance assemblies with low VSWR characteristics. The standard connectors include, MCX, SMA, TNC, Type N, and precision
10、Type N. Gore can also offer special performance connectors for specific requirements, please contact Gore for details.
