DC-18 GHz 50 Ohm Flexible Shielded RF Cable Low Loss Coaxial Cable for Vna Test with Silvered Copper Conductors

This RF cable is offered as a shielded coaxial cable for RF signal transmission. It is specified with 50 ohm impedance and a DC to 18 GHz operating range, together with an 83% velocity value. Its stated construction includes a silvered copper center conductor, low-density PTFE dielectric, tape-wrapped inner shield, braided outer shield, and grey PFA/FEP jacket.

The listed construction has an 8.10 mm finished outside diameter and a 2.40 mm silvered copper center conductor. It includes a 6.41 mm low-density PTFE dielectric, 6.55 mm silvered copper tape-wrapped inner shield, and 7.10 mm braided silvered copper wire outer shield. The supplied information describes the cable itself rather than a terminated assembly.

The cable is specified for DC to 18 GHz operation, with shielding effectiveness greater than 90 dB and voltage withstanding of 3000 V DC. Flexure-related values are amplitude stability below +/-0.1 dB and mechanical phase stability below +/-5 degrees. At 25 degrees C and sea level, typical attenuation increases from 0.07 dB/m at 300 MHz to 0.63 dB/m at 18000 MHz. The associated tabulated power values change from 4448 W at 300 MHz to 519 W at 18000 MHz

No connector interface, mating standard, or connector compatibility is specified for this RF cable. Available electrical compatibility information includes 50 ohm impedance and DC to 18 GHz operation. The stated temperature range is -55 to +165 degrees C, while the static and dynamic bend radii are 41 mm and 81 mm respectively. These separate bend-radius values distinguish static installation guidance from dynamic bending guidance

For selection or inquiry, provide the required operating frequency and compare it with the stated DC to 18 GHz range. Identify the applicable point on the typical attenuation/power curve, which is provided at 25 degrees C and sea level. Confirm whether the installation is static or dynamically flexed because the specified bend radii are 41 mm and 81 mm respectively.
