The invention provides a high-frequency phase-stable cable, which comprises an outer sheath, an electrical core and supporting units. The supporting units are laminated in order. The top end of one lower supporting unit is inserted into an opening of the bottom end of one upper supporting unit. The top end of one lower supporting unit ends under a fixing part. The bottom end of one upper supporting unit ends in a contact line of one lower supporting unit, and the contact line is the uppermost contact line of the lower supporting unit. The high-frequency phase-stable cable is different from a conventional filled type phase-stable cable. The supporting units are adopted to serve as supports between a conductor metal core inside a coaxial cable and a metal housing sheath, so that mediums are not completed filled between the metal core of the coaxial cable and the housing sheath, deformation of the cable caused by temperature changes is much reduced that that of a conventional cable, and phase fluctuations of the phase-stable cable are much smaller. Meanwhile, the cable can better restore after deforming under the effect of external force so as to exhibit higher mechanical strength.
Description
technical field [0001] The invention relates to the technical field of coaxial cables, in particular to a high-frequency phase-stable cable and a supporting unit thereof. Background technique [0002] High-frequency phase-stable cables are one of the most widely used varieties of coaxial cables. It has the characteristics of small attenuation, low standing wave, and stable phase. It is mainly used in phased array radars, radio telescopes, satellites and other environments that require high phase stability indicators. High-performance stable coaxial cables are produced in large quantities by professional manufacturers in the United States, the European Union, Russia and other countries, and are widely used in high-performance testing instruments and weaponry. The high-end phase-stable cable assemblies currently used in my country are almost entirely dependent on imports. The main reason is that domestic high-frequency phase-stable cables use dielectric-filled coaxial cables,...
