DC to 67 GHz High-Stability Phase-Stable Armored RF Cable for Test Interconnection

This RF cable is offered for high-stability, amplitude- and phase-stable RF test interconnection. It has 50 ohm impedance and an operating range from DC to 67 GHz. The supplied specifications cover electrical, mechanical, and environmental cable characteristics, including flexure-related amplitude stability and mechanical phase stability. They do not identify a connector type or a specific connected instrument

The listed configuration uses a 0.50 mm silvered-copper center conductor, LD-PTFE dielectric and middle layer, silvered-copper tape inner shield, braided silvered-copper-wire outer shield, FEP jacket, and compound-material armor. The final outside diameter is 4.80 mm. The supplied information specifies the cable construction and performance parameters, but does not list cable length, connector assemblies, or included accessories

The cable is specified for DC to 67 GHz operation with 50 ohm impedance and 81% velocity. Amplitude stability versus flexure is below +/-0.05 dB, while mechanical phase stability is below +/-5 degrees. At the stated 25 deg C and sea-level conditions, typical attenuation increases from 0.35 dB/m at 300 MHz to 5.93 dB/m at 67 GHz. The corresponding listed power values change from 203 W at 300 MHz to 12 W at 67 GHz

The cable structure includes a silvered-copper tape inner shield and a braided silvered-copper-wire outer shield, with shielding effectiveness greater than 90 dB. An FEP jacket and compound-material armor form the outer construction, which has a 4.80 mm final outside diameter. Specified environmental and mechanical values include -55 to +125 deg C operation, 24 mm static bend radius, 48 mm dynamic bend radius, and 100,000 bending times.

For selection, compare the required signal path with the DC to 67 GHz operating range and 50 ohm impedance. Check installation routing against the 24 mm static bend radius and 48 mm dynamic bend radius, as well as the specified -55 to +125 deg C temperature range. For frequency-related assessment, refer to the typical attenuation and power pair at the relevant frequency; these values are stated at 25 deg C and sea level.
