Description
Technical field
The utility model relates to radio-frequency cable component field, specifically a kind of radio-frequency cable component phase surveys auxiliary dress fastly
It sets.
Background technique
Since modern war is higher and higher to weapon system requirement, militarily, phased array radar has obtained extremely extensive
Using thus in recent years, highly reliable, high performance phase CA cable assembly have developed rapidly, performance is continuously improved, using also increasingly
Extensively, such as radar receiver and antenna-feeder system and satellite antenna-feeder system suffer from a very wide range of purposes, this is because usually more
Use broadband imaging technology in the phased-array radar of road receiver, either to single channel receiver magnitude-phase characteristics with interior fluctuating,
Or the amplitude-phase consistency between the receiver of plaid matching Shandong proposes particular/special requirement.Therefore receiver and with interior amplitude and phase all the way
The increase that position rises and falls will increase the amplitude of pared echo.So that the distortion of Range profile is caused, and the amplitude between multipath receiver
The inconsistent directional diagram that will affect antenna, to influence accuracy and angle, the Sensor gain and phase perturbations between them not only influence
Accuracy and angular resolution.And influence to be added while multipath reception signal, make the broadening of useful signal main lobe to influence
The resolving power of distance.
So phased-array radar does not require nothing more than low-loss, low standing wave, highly reliable to radio-frequency cable component, and to radio frequency
CA cable assembly phase equalization proposes extremely harsh requirement, this be to entire radar and weapon system it is vital, it is existing
The CA cable assembly of modern this excellent properties have developed rapidly in recent years, and application is also more and more extensive.
But phase equalization precision when due to radio-frequency cable manufacture has certain gap with respect to radar system permissible accuracy,
So need to be carried out CA cable assembly with phase according to the phase equalization precision that radar system requires in radio-frequency cable component manufacture
Work.Match phase technique according to current domestic CA cable assembly, after CA cable assembly is completed for the first time, passes through vector network analyzer
Test phase calculates the physical length of difference phase by formula, after internal and external conductor is then scalded tin thawing with electric heating, uses
Cutter truncates cable, with the precision of calliper to measure control physical length, then again with electric heating by connector internal and external conductor
Soldering is fixed, and after CA cable assembly is completed for the first time, then by Network Analyzer test phase, is repeated until reaching requirement
Phase equalization precision.
Currently, domestic currently used CA cable assembly matches phase technique, there are following disadvantages:
1) production duration is longer, and production efficiency is low
With the development of the continuous development of microwave technology, especially Military Electronic Equipment, the frequency of use of electronic equipment is got over
Carry out higher, the cable group that according to the current country uses also higher and higher to the phase equalization requirement of steady phase radio-frequency cable component
Part operates level with phase technique and personnel, and the phase accuracy (± 5 ° of@4GHz) of lower requirement is generally 2 times with phase number, compared with
The phase accuracy (± 5 ° of@18GHz) of high request is generally 4 times with phase number, phase accuracy (± 5 ° of@of rigors
Phase number of matching 40GHz) is generally 8 times.
So when matching phase every 1 time, require to carry out connector internal and external conductor to scald that tin melts, soldering is fixed and connector
Disassembly, assembling, general 1 time match phase when be about at least 10 minutes, duration is more.
2) higher cost
Match phase technique according to currently used CA cable assembly, when matching phase every 1 time, since internal and external conductor all needs to carry out scalding tin
Thawing and again soldering are fixed, and are scalded in the internal and external conductor welding hole after tin melts due to retaining remaining scolding tin, can not be removed completely,
Gold plated Layer influence welding quality can be destroyed if removing by mechanical means, and internal and external conductor size can be changed to influence after welding
Concentricity between connector and cable, so influence CA cable assembly electric property, therefore generally by boiling hot tin thawing remove inside and outside lead
Body is rejected, and the inner conductor more renewed carries out soldering again and fixes.
So the part loss of 1 set of inner conductor, outer conductor, higher cost will be brought when matching phase every 1 time.
3) performance quality is influenced
Match phase technique according to currently used CA cable assembly, when matching phase every 1 time, 2 electricity need to be carried out to internal and external conductor and added
Heat.The steady phase radio-frequency cable component of high-performance is generally adopted by the radio-frequency cable of the steady mutually series of ultra-low loss fixed ampllitude, according to cable
Composed structure, the dielectric layer of cable is polytetrafluoroethylene (PTFE) twining package tape, and the linear expansion coefficient of polytetrafluoroethylene material is more a height of
1.17×10-4Mm/ DEG C, when matching phase, electrically heated temperature is up to 200 DEG C or more, though instantaneous high-temperature also can be to welding section
Cable dielectric layer brings larger size to influence, and cable dielectric layer can be axially extended, and reply room temperature after can not complete resizing,
The extra medium of stretching can only be cut off with cutter, influence the dielectric permittivity of welding section cable, and then influence electric property.
And when matching phase every 1 time, 2 electric heating all carried out affect the welding quality of cable shield.
