DC to 18 GHz 50 Ohm Multi-Layer Shielded RF Cable with FEP Jacket

This listing covers an RF cable with 50 Ohm impedance and a specified operating range from DC to 18 GHz. Its documented construction includes a silvered-copper center conductor, low-density PTFE dielectric, inner and outer braided shielding layers, an aluminum-foil layer, and an FEP jacket. Shielding effectiveness is specified as greater than 90 dB, while voltage withstanding is specified as 2000 V DC.

The documented cable construction starts with a 1.57 mm silvered-copper center conductor and finishes with a 6.35 mm FEP jacket. The intermediate layers are a low-density PTFE dielectric, braided silvered-copper-tape inner shield, high-temperature aluminum foil, and braided silvered-copper-wire outer shield. The specified finished cable weight is 93 g/m. Connector types, supplied assembly length, and additional items are not identified in the provided parameter table

Typical attenuation and power values are stated at 25 C and sea level. Attenuation increases from 0.12 dB/m at 300 MHz to 1.02 dB/m at 18000 MHz, while the corresponding listed power changes from 1885 W to 221 W. At 6000 MHz, the listed values are 0.56 dB/m and 401 W; at 12400 MHz, they are 0.83 dB/m and 271 W. These values are typical data under the stated measurement conditions

The RF cable is specified for DC to 18 GHz operation with 50 Ohm impedance and 76% velocity. Its static bend radius is 32 mm and its dynamic bend radius is 64 mm, so the stated dynamic routing radius is larger than the static value. The specified operating temperature range is -55 to +200 C, and voltage withstanding is 2000 V DC. Connector interface, mating standard, and equipment compatibility are not stated in the provided table

For selection, compare the required frequency range with the specified DC to 18 GHz operating range and review the typical attenuation data at the intended frequency. The listed attenuation and power values are measured at 25 C and sea level, which should be considered during evaluation. Confirm that installation conditions are within the -55 to +200 C temperature range and that routing meets the 32 mm static or 64 mm dynamic bend radius.
