Flexible Low-Loss Shielded Flexible Microwave Coaxial Cable with Amplitude Phase Stability for Vna Test Measurement System

This product is a shielded RF coaxial cable for RF signal transmission. It is specified for DC-18 GHz operation and has a 50 ohm cable impedance. The listed construction includes a silvered copper center conductor, low-density PTFE dielectric, silvered copper tape inner shield, braided silvered copper outer shield, and a grey PFA/FEP jacket. No connector, cable assembly, or end termination is identified in the supplied specifications

The supplied information specifies the cable itself with a 5.60 mm finished outer diameter and grey PFA/FEP jacket. Its internal structure includes a 1.60 mm silvered copper center conductor, 4.30 mm low-density PTFE dielectric, and two silvered-copper shield layers. The source does not state a standard cut length, connector type, or included accessories. Buyers should confirm any required cable length and termination arrangement separately before ordering

The cable is specified for DC-18 GHz operation, 50 ohm impedance, and 83% velocity. Amplitude stability versus flexure is below +/-0.1 dB, while mechanical phase stability is below +/-5 deg. At 25 deg C and sea level, typical attenuation rises from 0.12 dB/m at 300 MHz to 0.96 dB/m at 18000 MHz. The corresponding listed typical power values decrease from 2256 W at 300 MHz to 286 W at 18000 MHz

The cable uses a silvered copper tape inner shield and braided silvered copper wire outer shield, with shielding effectiveness specified above 90 dB. It has a 5.60 mm finished cable diameter and static and dynamic bend radii of 28 mm and 56 mm, respectively. The specified temperature range is -55 to +165 deg C, and voltage withstanding is 2000 V DC. System compatibility should be evaluated against the required 50 ohm impedance, frequency range, and routing conditions

For selection, buyers should compare their required frequency range with the specified DC-18 GHz range and confirm that a 50 ohm cable is suitable for their system. Required cable routing should be checked against the 28 mm static and 56 mm dynamic bend radii, together with the 5.60 mm cable outer diameter. Environmental requirements can be compared with the -55 to +165 deg C temperature range and 2000 V DC withstand value.
