DC to 18 GHz 50 Ohm RF Test Cable with PTFE Dielectric and FEP Jacket

This offering is an RF test cable for high-stability RF test interconnection. It has 50 ohm impedance and is specified for operation from DC to 18 GHz. Its construction includes a silvered copper center conductor, solid PTFE dielectric, multilayer shielding, and an FEP jacket. The supplied data also state amplitude stability versus flexure of less than +/-0.1 dB and mechanical phase stability of less than +/-5 deg

The listing covers the specified RF test cable configuration with a 4.88 mm FEP-jacket outer diameter and a weight of 58 g/m. Its shielding layers comprise silvered copper tape wrapping, high-temperature aluminum foil, and braided silvered copper wire. The supplied specifications do not identify cable length, connector type, termination style, or delivered assembly details. These items should therefore be confirmed when discussing the required configuration

The cable is specified for DC to 18 GHz operation with 50 ohm impedance, 70% velocity, and 1500 V DC voltage withstanding. Shielding effectiveness is greater than 90 dB, while amplitude stability versus flexure is less than +/-0.1 dB and mechanical phase stability is less than +/-5 deg. At 25 deg C and sea level, typical attenuation changes from 0.21 dB/m at 300 MHz to 2.24 dB/m at 18000 MHz. The listed power values change from 932 W to 87 W across those same frequency points

The cable uses a 0.94 mm silvered copper center conductor and a 2.98 mm solid PTFE dielectric. It has three specified shield layers, followed by an FEP jacket with a 4.88 mm outer diameter. The temperature range is -55 to +125 deg C, with 24 mm static and 48 mm dynamic bend radii. Connector interfaces and compatibility with particular connector types are not identified in the supplied data

Selection should compare the required operating range with the specified DC to 18 GHz range and verify that 50 ohm impedance is suitable for the intended interconnection. Routing should account for the 4.88 mm jacket outer diameter, 24 mm static bend radius, and 48 mm dynamic bend radius. For an inquiry, provide the required cable length and required connector or termination details. These deliverable details are not stated in the supplied parameter table
