DC to 18 GHz 50 Ohm Shielded RF Coaxial Cable with Low-Density PTFE Dielectric

This listing is a shielded RF coaxial cable for RF signal transmission. It is specified with a DC to 18 GHz operating range and 50 ohm cable impedance. The published data also states amplitude stability versus flexure below +/-0.1 dB and mechanical phase stability below +/-5 degrees. Connector terminations, supplied cable length, cable assemblies, and specific end-use applications are not identified in the available specifications

The cable construction includes a 3.00 mm silvered-copper center conductor, an 8.24 mm low-density PTFE dielectric, and a grey PFA/FEP jacket with a 10.00 mm finished outside diameter. Its shielding layers are silvered-copper tape at 8.48 mm and braided silvered-copper wire at 9.20 mm. The published table provides construction details, but it does not state a supplied length, connector terminations, accessories, or other included deliverables

The cable is specified for DC to 18 GHz operation, with 50 ohm impedance, 83% velocity, shielding effectiveness above 90 dB, and 3000 V DC voltage withstanding. Typical attenuation at 25 degrees C and sea level is 0.06 dB/m at 300 MHz and 0.36 dB/m at 10000 MHz. The corresponding typical power values are 6539 W and 1016 W. Additional typical curve points are provided at 1000, 3000, 6000, and 8500 MHz

This RF coaxial cable has a silvered-copper center conductor, low-density PTFE dielectric, silvered-copper tape inner shield, braided silvered-copper outer shield, and grey PFA/FEP jacket. The finished outside diameter is 10.00 mm, with specified static and dynamic bend radii of 50 mm and 100 mm. Its operating temperature range is -55 to +165 degrees C. Connector type, mating-interface details, and compatibility with particular equipment are not provided

For selection, compare the required operating range with the specified DC to 18 GHz range and confirm that 50 ohm impedance suits the system. Check routing conditions against the 50 mm static bend radius and 100 mm dynamic bend radius. Review the typical attenuation and power curve at the frequency of interest, noting that the values are stated at 25 degrees C and sea level. For an inquiry, provide the required cable length and termination details, which are not listed
