Abstract
The invention discloses a test level cable which comprises: an inner conductor (1) and an external dielectric layer (2). The cable is characterized in that: the inner conductor (1) is made of silver-plated copper; the dielectric layer (2) is made of PTFE; the dielectric layer (2) winds around the inner conductor (1) through a wrapping mode. Because of a special structure of the invention, during usage, stability of cable amplitude and phase can be maintained, high precision and good consistency of a tested device can be ensured. And a voltage standing wave ratio (VSWR) is less than 1.3 @ 40 GHz, phase stability of a product is less than 8.0 DEG @40 GHz/minus 8.0 DEG @40 GHz and an insertion loss change of the assembly is less than 0.1 dB @40 GHz. Therefore, consistency and stability of a performance index of the invention is good; VSWR is low; phase and amplitude stabilities are excellent.
Description
Technical field
The present invention relates to a kind of cable, relate in particular to a kind of testing-level cable that is applicable to the radio frequency parameter measurement of radio-frequency devices.
Background technology
Along with the extensive development of domestic 4G mobile communication, broadband metropolitan area network, WLAN (wireless local area network), all kinds of radio-frequency devices are widely used in the wireless communication system, and the research and development of radio-frequency devices, design and production are flourish at home.All radio-frequency devices must carry out the measurement of radio frequency parameter before dispatching from the factory, to guarantee stability and the consistency of product when the high frequency.This makes the radio-frequency measurement system by communication experiment chamber, the large-scale demand of radio-frequency devices manufacturer, but until today, this high-end market is monopolized by external well-known a few large manufacturer all the time.The radio-frequency measurement system forms as network analyzer and measurement cable assembly generally by measuring equipment.The measurement cable assembly is the bridge between measuring equipment and the test product, if test cable is selected bad, to take in the test data of tested components and parts by the fluctuation of measuring the cable generation easily, the error of its generation directly influences the accuracy of test data, it is unstable to cause radio frequency products to occur in the middle of reality is used, problems such as electricity function index difference, and the performance of present domestic testing-level cable and quality are uneven: a lot of producers adopt common telecommunication cable assembly to serve as testing-level cable, mechanical phase stability to cable, important indicators such as machinery range stability are not done any requirement and regulation, fundamentally can't guarantee the consistency and the stability of the performance index of the product of surveying.
Summary of the invention
The objective of the invention is to overcome that performance index such as the consistency that exists in the prior art and stability are relatively poor, voltage standing wave(VSW) is bigger, the steady phasic property of fixed ampllitude is poor, the defective of bending property difference repeatedly, the consistency that a kind of performance index are provided and stability are better, voltage standing wave(VSW) is smaller, the steady phasic property of fixed ampllitude is good, the good testing-level cable of bending property repeatedly.
Technical scheme of the present invention provides a kind of testing-level cable, comprises inner wire and outside dielectric layer thereof, and described dielectric layer surrounds inner conductor by the mode of twining.Dielectric layer is a kind of PTFE band, and PTFE is resistant to elevated temperatures polytetrafluoroethylene.Dielectric layer is outward that silver-plated copper strips is wrapped, and silver-plated copper strips outside is twined one deck PTFE band again, carries out the silver-gilt copper wire establishment then, the restrictive coating that final high temperature is extruded.The material of restrictive coating is MFA, i.e. the fluoroplastics particle.
Beneficial effect of the present invention is: because special construction of the present invention, during use, the stability that can keep cable amplitude and phase place, guarantee that simultaneously measured device has high accuracy and good consistency, and voltage standing wave ratio VSWR＜1.340GHz, phase change number of degrees Phase Stability＜± 8.0 ° of 40GHz of product, the Insertion Loss variation＜0.1dB 40GHz of assembly.Therefore the present invention not only performance index consistency and stability better, voltage standing wave ratio is ultralow, and has good phase place and range stability.
