DC to 18 GHz 50 Ohm Shielded Internal Interconnect RF Cable with Silvered Copper and FEP Jacket

This product is an internal interconnect RF cable for electrical and RF signal interconnection. It is specified with 50 ohm impedance and an operating frequency range from DC to 18 GHz. The available information covers cable construction, electrical properties, mechanical limits, environmental range, and typical attenuation and power values. No specific end-use application is identified in the supplied product data

The listing documents one defined cable construction rather than multiple listed configurations. It includes a silvered copper center conductor, low-density PTFE dielectric, silvered copper tape inner shield, braided silvered copper wire outer shield, and an FEP jacket. The finished jacket outer diameter is 7.00 mm, and the listed cable weight is 118 g/m.

Typical attenuation and power values are provided at 25 deg C and sea level across the listed frequency points. Attenuation changes from 0.13 dB/m at 300 MHz to 1.63 dB/m at 18000 MHz, while the corresponding listed power changes from 1100 W to 88 W. The cable is also specified with shielding effectiveness above 90 dB and voltage withstanding of 3000 V DC. These values should be compared at the applicable operating frequency and stated conditions

The cable uses a 1.63 mm silvered copper center conductor and a 5.30 mm low-density PTFE dielectric. Its shielding structure comprises a 5.55 mm silvered copper tape inner shield and a 6.17 mm braided silvered copper wire outer shield, beneath a 7.00 mm FEP jacket. The specified static bend radius is 35 mm, while the dynamic bend radius is 70 mm. Connector type and connector compatibility are not specified, and the stated temperature range is -55 to +125 deg C

For selection, compare required system impedance and frequency range with the specified 50 ohm and DC to 18 GHz values. Review attenuation and listed power together because both are provided by frequency under 25 deg C, sea-level conditions. Installation planning should consider the 7.00 mm jacket diameter, 35 mm static bend radius, 70 mm dynamic bend radius, and temperature range of -55 to +125 deg C.
