DC to 18 GHz 50 Ohm Low-Loss RF Cable with Silvered Copper Conductor and PFA Jacket

This offering is an economical low-loss RF cable for signal transmission. Its stated electrical scope is 50 ohm impedance and operation from DC to 18 GHz, with a listed velocity of 76%. The documented construction includes a silvered copper center conductor, low-density PTFE dielectric, aluminum-foil inner shield, braided silvered copper outer shield, and PFA jacket.

The supplied information documents one RF cable construction. It uses a 0.91 mm silvered copper center conductor and a 2.65 mm low-density PTFE dielectric, followed by a 2.78 mm self-adhesive aluminum-foil inner shield and a 3.15 mm braided silvered copper outer shield. The finished cable has a bluish PFA jacket with a 3.60 mm outer diameter and a listed weight of 29 g/m. Cut length, connector termination, package quantity, and other deliverables are not stated

Typical attenuation at 25 degrees C and sea level increases from 0.21 dB/m at 300 MHz to 1.72 dB/m at 18000 MHz. The corresponding listed power values decrease from 980 W at 300 MHz to 120 W at 18000 MHz, with intermediate data provided at 1000, 3000, 6000, 8500, and 12400 MHz. Shielding effectiveness is specified as above 70 dB, and voltage withstanding is listed as 1500 V DC. These values are provided for the stated test condition of 25 degrees C at sea level

No connector type or equipment interface is specified, so connector compatibility is not defined by the supplied data. The cable has a 3.60 mm outer diameter, while its stated static bend radius is 18 mm and dynamic bend radius is 36 mm. Its shielding structure combines self-adhesive aluminum foil with braided silvered copper wire beneath a bluish PFA jacket. The listed operating temperature range is -55 to +125 degrees C

For selection, compare the required impedance and frequency range with the listed 50 ohm and DC to 18 GHz values. Attenuation and power requirements can be checked against the typical 25 degrees C, sea-level data, which spans 300 MHz through 18000 MHz. Mechanical requirements should be compared with the 3.60 mm outer diameter, 29 g/m weight, and 18 mm static or 36 mm dynamic bend radius.
