DC to 26.5 GHz 50 Ohm Phase Stable RF Test Cable Phase Stable Cable with FEP Jacket

This listing covers an RF test cable intended for RF test interconnection. It is specified with 50 ohm cable impedance and an operating frequency range from DC to 26.5 GHz. The documented construction includes a silvered copper center conductor, low-density PTFE dielectric and middle layers, silvered copper inner and outer shielding layers, and an FEP jacket. No end-use application beyond RF test interconnection is identified in the supplied data

The available specifications define the cable construction rather than a finished connectorized assembly. They identify a 1.30 mm silvered copper center conductor, low-density PTFE layers, a silvered copper tape inner shield, a braided silvered copper outer shield, and a 5.20 mm FEP jacket outer diameter. The cable weight is specified as 68 g/m. Finished length, connector type, and included accessories are not stated and should be confirmed separately

The cable is specified for DC-26.5 GHz operation, with 50 ohm impedance and 76% velocity. Its amplitude stability versus flexure is below +/-0.1 dB, while mechanical phase stability is below +/-5 deg. Shielding effectiveness is greater than 90 dB, and voltage withstanding is 1000 V DC. At 25 deg C and sea level, typical attenuation increases from 0.14 dB/m at 300 MHz to 1.41 dB/m at 26500 MHz, while the corresponding listed power changes from 1382 W to 132 W

The structure uses silvered copper tape wrapping as the inner shield and braided silvered copper wire as the outer shield. The FEP jacket outer diameter is 5.20 mm, with a 26 mm static bend radius and a 52 mm dynamic bend radius. The stated temperature range is -55 to +165 deg C. Connector interfaces and mating requirements are not identified in the available information, so they should be confirmed for the intended cable assembly

Confirm that the required system impedance is 50 ohm and that the intended operating range is within DC-26.5 GHz. Review the published attenuation and power relationship at the relevant frequency, because these values are stated at 25 deg C and sea level. Installation planning should consider the 5.20 mm jacket outer diameter and the separate 26 mm static and 52 mm dynamic bend radii.
