DC to 18 GHz 50 Ohm Coaxial RF Cable with Silvered Copper and PFA Jacket

This listing covers a coaxial RF cable for economical low-loss signal transmission. The specified cable has 50 ohm impedance and an operating frequency range from DC to 18 GHz. Its construction includes a silvered copper center conductor, low-density PTFE dielectric, aluminum foil inner shield, and braided silvered copper outer shield. The listed operating temperature range is -55 to +125 degrees C

The listing defines one specified coaxial cable construction rather than a range of connectorized assemblies. It has a 1.45 mm silvered copper center conductor, 4.20 mm low-density PTFE dielectric, and a bluish PFA jacket with 5.20 mm outer diameter. The shielding layers are self-adhesive aluminum foil and braided silvered copper wire. Cable length, connector terminations, and package contents are not specified in the supplied parameters

Typical attenuation and power values are provided at 25 degrees C and sea level across multiple frequency points. Attenuation is listed as 0.13 dB/m at 300 MHz and 1.16 dB/m at 18000 MHz, while the corresponding power values are 1935 W and 213 W. At 3000 MHz, the listed values are 0.43 dB/m and 580 W; at 6000 MHz, they are 0.62 dB/m and 397 W. These are typical values under the stated conditions

The cable uses a 50 ohm coaxial structure and is specified from DC to 18 GHz. Its shielding structure combines a self-adhesive aluminum foil inner layer with a braided silvered copper outer layer, with shielding effectiveness above 70 dB. The PFA jacket has a 5.20 mm outer diameter, and the stated static and dynamic bend radii are 26 mm and 52 mm. Connector types, mating interfaces, and equipment compatibility are not specified

For selection, confirm that the required system impedance is 50 ohm and that the operating frequency is within the DC to 18 GHz range. Check the installation route against the 26 mm static bend radius or 52 mm dynamic bend radius, depending on the installation condition. Environmental review can use the -55 to +125 degrees C temperature range and 2000 V DC voltage-withstanding value.
