Embodiment 1

[0015] Embodiment 1: as figure 1 , figure 2 Shown: a stable coaxial cable that is easy to process and has a linear phase-temperature relationship. The inner layer outer conductor (3) outside the insulating layer (2), the outer layer outer conductor (4) arranged outside the inner layer outer conductor (3), and the outer layer outer conductor (4) are provided with a protective layer (5), It is characterized in that the insulating layer (2) arranged outside the inner conductor (1) of the cable is made of polytetrafluoroethylene (PTFE) foam material. Polytetrafluoroethylene (PTFE) foam material is directly foamed from polytetrafluoroethylene (PTFE), and the foaming agent is polycyclic aromatic hydrocarbon.

[0016] The manufacturing method of the tetrafluoroethylene foam material comprises the following steps: resin type selection--drying--mashing--screening foaming agent--ball milling--screening--mixing--preforming--drying-- Cooling--analysis--sintering--cooling--finished pro...

Abstract

The invention provides an e asy-to manufacture stable phase coaxial cable having linear phase-temperature relation and a manufacture method of tetrafluoroethylene foam material thereof. The cable includes a cable inner conductor (1), an insulation layer (2) arranged outside the cable inner conductor (1), an inner layer outer conductor (3) arranged outside the insulation layer (2), an outer layer outer conductor (4) arranged outside the inner outer conductor (3), a protection layer (5) arranged outside the outer layer outer conductor (4). The insulation layer (2) arranged outside the cable inner conductor (1) adopts the tetrafluoroethylene foam material. The cable provided by the invention can be applied to an antenna feeder system used for a mobile communication base station. The attenuation of the cable in 6GHz IS 1.85Db / m and is 3.3 dB / m and the testing temperature is 20 DEG C. The cut-off frequency of the cable is 80 GHz and the transmission speed ratio is greater than 82%. The phase change range of the cable between 60 to 100 DEG C is between -10 ppm and 500 ppm and is far lower than the change range (-50 ppm to 1300 ppm) of a coaxial cable of micropore PTFE tape lapping insulation.

Description

technical field [0001] The invention relates to a radio frequency coaxial cable product and its manufacturing process in the field of communication transmission, and specifically belongs to a stable coaxial cable that is easy to process and has a linear phase-temperature relationship. The insulating layer of the cable is made of polytetrafluoroethylene (PTFE) foam material Extrusion processing technology, and finally make a cable that can be used in the antenna to replace the solid insulated PTFE cable, and can also be used for the external connection cable of the antenna to replace the foam polyolefin insulated corrugated copper tube outer conductor RF coaxial cable. Due to the reduced attenuation and high temperature resistance, this type of cable can greatly increase the feed power. When the attenuation and feed power requirements are constant, the cable specification can be reduced and the cable installation space can be saved. It is especially suitable for antennas with co...
