Description
Technical field
the utility model relates to armament systems and phased array radar communication technical field, particularly relates to a kind of foaming band lapped insulation high frequency of anti-flexure type phase-compensated cable.
Background technology
Because modern war is increasingly high to weapon system requirement, militarily, phased array radar has obtained using extremely widely
.Adopt accurate definite rocket of phase-compensated cable or satellite in the position in outer space like large-scale satellite tracking station, large-scale astronomical platform phase-compensated cable also capable of using comes the time signal of transmission standard.Thereby its stability of the stube cable that in phased array radar, uses is wanted to closing.Phased array radar adopts the broadband imaging technique, and no matter this technology is to rise and fall in the band to single channel receiver magnitude-phase characteristics, still the amplitude-phase consistency between the multipath receiver has all been proposed specific (special) requirements.The increase of amplitude and phase fluctuation will increase to the amplitude to echo in the band of single channel receiver, thereby cause the distortion apart from elephant; And the inconsistent directional diagram that will influence antenna of the amplitude between the multipath receiver; Thereby influence accuracy and angle; Phase place inconsistency between them not only influences accuracy and angular resolution, and addition when influencing the multipath reception signal; Make useful signal main lobe broadening, thereby influence the resolving power of distance.So phased array radar not only requires low-loss, low standing-wave ratio, highly reliable to cable, and very harsh requirement has been proposed for CA cable assembly phase equalization and stability.And a kind of polytetrafluoroethylene (PTFE) material that uses at present adopts and pushes sintering process and process that its decay of phase-compensated cable of solid insulating barrier is big, phase-unstable seriously restricts its use; Another kind is the superpower phase stability of silicon dioxide insulator high frequency phase-compensated cable when high low temperature, but the silicon dioxide insulator phase-compensated cable is the cable of tubular metal, so be not suitable for often crooked in use occasion, can only install and fix use.
are in view of the deficiency of above cable; Press for a kind of novel promptly soft have again low-loss, low standing-wave ratio, highly reliable high frequency phase-compensated cable, satisfy the demand in high speed development military electronics fields such as phased array radar, military electronic warfare equipment, digitlization advanced electronic system.
Present main phase-compensated cable type:
1, real core polytetrafluoroethylene (PTFE) insulated high frequency phase-compensated cable:
have single or stranded silver-plated tough copper conductor, solid-core polyfluortetraethyleinsulating insulating layer, silver-gilt copper wire braid shielded and fluoroplastics sheath to constitute from the inside to the outside.Utilize common polytetrafluoroethylene (PTFE) material employing to push sintering process and process solid insulating barrier; Its relative dielectric constant is 2.0 ~ 2.1; This kind structural cable transmission speed ratio is 69%, and (speed ratio is the ratio of signal transmission speed and transmission speed in air in cable; This value is the bigger the better), cause signal attenuation bigger.And adopt polytetrafluoroethylene (PTFE) material foaming expressing technique to the conductor as insulating barrier but technology prematurity still.With WXFWF-50-5A is example, adopts insulation to be real core polytetrafluoroethylene, and its relative dielectric constant is ε=2.1, and when conductor diameter is 1.45mm, when impedance was 50 Ω, it calculates insulation diameter was 4.85mm, greater than desired 3.99mm, can not satisfy specification requirement; Push sintering process if adopt, when expanded polytetrafluoroethyl(ne was adopted in insulation, foam degrees was 57.3%; Density is 0.94g/cm3; DIELECTRIC CONSTANTS=1.47, when impedance is 50 Ω, the inner wire diameter is 1.45mm; The outer conductor diameter is 3.99mm, but pushes the expanded polytetrafluoroethyl(ne insulating process is that all right ripe.
2, silicon dioxide insulator high frequency phase-compensated cable:
have the tough copper conductor of single high-purity (OFHC), the insulation of high foaming rate low-loss silica, high-purity oxygen-free copper (OFHC) steel pipe outer conductor and stainless steel or Titanium oversheath to constitute from the inside to the outside.High foaming rate (greater than the 80%) silicon dioxide insulating layer of different explained hereafter, make dielectric loss very low: dielectric constant has only 1.56, and can reduce signal decline and loss also reduced electric capacity simultaneously, increased transmission rate (reach the light velocity 80%).Can bear high radio frequency transmission power: being 5～20 times of unidimensional common PTFE cable, is to bear the highest cable of power at present in the world.But there is the restriction of bending radius by the high frequency phase-compensated cable that metal material is made, can not moves the problem of use, increase cable weight simultaneously, also be unfavorable for equipping the raising of vitality.
therefore demand developing a kind of reduction signal attenuation that reaches in the industry urgently, improve the phase-compensated cable of phase stability and cable transmission speed.
