DC to 26.5 GHz 50 Ohm Ultra-Low-Loss Phase-Stable Semi-Rigid RF Cable

This offering is a semi-rigid RF cable for ultra-low-loss, phase-stable RF interconnection. It has 50 Ohm impedance and is specified for operation from DC to 26.5 GHz. Its construction includes a silvered copper center conductor, a low-density PTFE dielectric, and a ternary-alloy-plated seamless annealed bare copper-tube outer conductor. The available data describes the cable itself and does not identify a particular end-use application or installation service

The documented product is a semi-rigid RF cable with a 1.05 mm center-conductor O.D., 3.00 mm dielectric O.D., and 3.58 mm outer-conductor O.D. Its specified weight is 45 g/m, and its bend radius is 13.5 mm. The available specifications do not state a connector type, finished cable length, pre-terminated assembly, or included accessories. These requirements should be confirmed separately when they are needed for purchasing

Typical attenuation and power values are stated at 25 C and sea level, and both vary with frequency. At 300 MHz, the listed values are 0.17 dB/m attenuation and 2060 W power, while at 26500 MHz they are 1.68 dB/m and 206 W. At 3000 MHz, the stated values are 0.54 dB/m and 641 W. Shielding effectiveness is greater than 165 dB, and voltage withstanding is specified as 1000 V DC

This RF cable has 50 Ohm impedance and is specified for operation from DC to 26.5 GHz. Its semi-rigid structure combines a 3.58 mm O.D. plated seamless copper-tube outer conductor with a 3.00 mm O.D. low-density PTFE dielectric. The stated temperature range is -55 to +250 C, and the bend radius is 13.5 mm. Connector interfaces and compatibility with a particular connector assembly are not identified in the available specifications

For selection, compare the required operating frequency with the stated DC to 26.5 GHz range and confirm that 50 Ohm impedance is suitable for the intended system. Review attenuation and typical power at the relevant frequency, because the values change from 0.17 dB/m and 2060 W at 300 MHz to 1.68 dB/m and 206 W at 26500 MHz. The 13.5 mm bend radius and -55 to +250 C temperature range should also be considered.
