DC-18GHz 50 Ohm Flexible Shielded RF Cable with Silvered Copper and PTFE Construction

This product is a shielded coaxial RF cable for RF signal transmission. It is specified with 50 ohm impedance and an operating frequency range from DC to 18 GHz. The documented cable characteristics also include amplitude stability versus flexure below +/-0.1 dB and mechanical phase stability below +/-5 deg. The available information defines a cable construction; connectorized assemblies, connector types, and complete system contents are not specified

The listed construction comprises a silvered copper center conductor, low-density PTFE dielectric, silvered copper tape inner shield, braided silvered copper wire outer shield, and grey PFA/FEP jacket. The finished outside diameter is 7.90 mm, while the specified weight is 130 g/m. Layer outside diameters are provided from 2.30 mm at the center conductor to 7.90 mm at the jacket.

This RF Cable is specified for DC-18 GHz operation with 50 ohm impedance and 83% velocity. Typical attenuation and power values are stated at 25 C and sea level, from 0.08 dB/m and 4246 W at 300 MHz to 0.67 dB/m and 507 W at 18000 MHz. At 6000 MHz, the listed values are 0.37 dB/m attenuation and 912 W power. Shielding effectiveness is above 90 dB, and voltage withstanding is 3000 V DC

The cable uses a coaxial structure with a silvered copper tape inner shield and braided silvered copper wire outer shield. Its specified impedance is 50 ohm, supporting selection for RF paths requiring the same impedance. The static bend radius is 39 mm, while the dynamic bend radius is 79 mm. The stated operating temperature range is -55 to +165 C, and connector interface details are not provided

When selecting this RF Cable, compare the required operating frequency with the stated DC-18 GHz range and confirm that the connected RF path requires 50 ohm impedance. Review mechanical requirements against the 7.90 mm finished diameter, 130 g/m weight, 39 mm static bend radius, and 79 mm dynamic bend radius. Environmental conditions can be compared with the -55 to +165 C temperature range.
