DC to 18 GHz 50 Ohm Phase Stable Shielded RF Test Cable with FEP Jacket

This listing covers an RF test cable for high-frequency, high-speed test interconnection. The specified operating range is DC to 18 GHz, and the cable has 50 ohm impedance. Its construction includes a silvered-copper center conductor, low-density PTFE layers, multiple shield-related layers, and an FEP jacket. The supplied information does not identify end connectors, finished cable length, or pre-terminated assembly details

The published information describes one defined cable construction rather than multiple listed construction choices. It includes a 0.51 mm silvered-copper center conductor, low-density PTFE dielectric, silvered-copper tape inner shield, aluminum-foil reinforcement, braided silvered-copper outer shield, and a 2.60 mm FEP jacket. Connectors, pre-terminated cable assemblies, and standard cut lengths are not specified in the supplied table.

The cable is specified for DC to 18 GHz operation, with 50 ohm impedance and 76% velocity. Shielding effectiveness is greater than 90 dB, while voltage withstanding is 500 V DC. Amplitude stability versus flexure is below +/-0.1 dB, and mechanical phase stability is below +/-5 degrees. Typical attenuation and power figures are published at 25 degrees C and sea level for frequency points from 300 MHz through 67000 MHz

The cable has a layered shield structure comprising silvered-copper tape wrapping, self-adhesive aluminum-foil reinforcement, and a braided silvered-copper outer shield. Its outer jacket is FEP, and the specified temperature range is -55 to +165 degrees C. The static bend radius is 11 mm, whereas the dynamic bend radius is 26 mm. Connector types and mating-interface compatibility are not identified in the supplied information and should be confirmed separately

For selection or quotation, provide the required cable length and whether cable ends need termination, since these details are not defined in the published table. Confirm that the DC to 18 GHz operating range and 50 ohm impedance match the intended system requirements. Where routing involves bending, compare the installation condition with the specified 11 mm static and 26 mm dynamic bend radii.
