DC-18 GHz 50 Ohm Shielded RF Cable with FEP Jacket for Test Interconnection

This listing covers an RF cable intended for test interconnection. It is specified for DC-18 GHz operation with 50 ohm impedance and uses a silvered copper center conductor with a low-density PTFE dielectric. The documented construction also includes multiple shielding layers and an FEP outer jacket. The available data describes the cable itself and does not identify a connector type, finished length, or accessory package

The cable construction begins with a 1.02 mm silvered copper center conductor and reaches 3.07 mm after the low-density PTFE dielectric. Shielding consists of braided silvered copper tape, high-temperature aluminum foil, and braided silvered copper wire before the FEP jacket, which gives a 4.60 mm finished outside diameter. The listed weight is 53 g/m. The available specifications do not identify a finished cable length, connector, or included assembly item

The cable is specified for DC-18 GHz operation. At 25 C and sea level, typical attenuation changes from 0.19 dB/m at 300 MHz to 1.58 dB/m at 18000 MHz, while the corresponding listed power values change from 1047 W to 127 W. Additional electrical data includes shielding effectiveness above 90 dB and a 1500 V DC voltage-withstanding value. These attenuation and power figures are frequency-specific typical values under the stated conditions

This RF cable has 50 ohm impedance and a listed velocity of 76%. Its finished outside diameter is 4.60 mm, with a 23 mm static bend radius and a 46 mm dynamic bend radius. The specified temperature range is -55 to +200 C, and the weight is 53 g/m. No connector or equipment-interface compatibility is stated in the available product data

For selection, compare the required operating range with the specified DC-18 GHz range and confirm that a 50 ohm cable is appropriate for the intended system. Check installation routing against the 23 mm static and 46 mm dynamic bend radii, and verify that the expected temperature is within -55 to +200 C. Where attenuation or power is important, use the listed frequency-specific typical values, which are stated at 25 C and sea level.
