Description
Technical field
The present invention relates to a kind of radio-frequency cable component assembly method, specifically a kind of radio-frequency cable component phase equalization dress
Method of completing the square belongs to radio-frequency cable component technical field.
Background technique
Radar has special sensibility to phase index, has between each CA cable assembly used in special sensitive requirements
There is the phase equalization requirement of certain precision, especially in phased-array radar and electronic countermeasure matching system, this requirement is more
It is stringent.
Before component assembly and when the installation and debugging of assembling process, component needs to have accurate electrical length.In order to guarantee
The consistency of each model inter-module electrical length, each radio-frequency cable component will carry out component to match phase in manufacture, installation and debugging.
This just needs that component is accurately cut, installs and tested, and is matched one by one, needs repeated multiple times can be only achieved sometimes
It is required that careless slightly will cause is cut excessive and is scrapped.
The amplitude-phase consistency matching of CA cable assembly is crucial technical problem.Width phase one of the development of product to CA cable assembly
The requirement of cause property is high, the consistency of same batch is not required nothing more than, also it is often required that different batches CA cable assembly has amplitude-phase consistency.
Cable to the maximum component of amplitude-phase consistency Index Influence, the material of cable, diameter, around packet mode, dielectric constant, frequency,
Length etc. all directly has an impact amplitude-phase consistency.
When matching phase, the phase difference between radio-frequency cable component is measured by vector network analyzer, corresponding to every degree
Length of cable size thread not equal (one is 0.01 millimeter) from several to more than ten.In radio-frequency cable component assembling process, by repairing
Length with cable adjusts phase, final to guarantee phase equalization between CA cable assembly.Existing phase method of matching is by multiple
Miscellaneous calculating carries out, and not only time-consuming fallibility, is also unfavorable for producing in batches.
Summary of the invention
The object of the present invention is to provide a kind of radio-frequency cable component phase equalization assembly method, which can be effective
Guarantee radio-frequency cable component between phase equalization.
In order to reach above-mentioned technical purpose, the technical scheme is that
A kind of radio-frequency cable component phase equalization assembly method, comprising the following steps:
(1) assembly for completing first radio-frequency cable component utilizes vector net on the basis of first radio-frequency cable component
The test of network analyzer；
(2) second radio-frequency cable component, one end of second radio-frequency cable component and a upper radio-frequency cable group are made
Part is matched by connector device；
(3) single channel test is carried out by vector network analyzer, and is compared with first radio-frequency cable component, obtain phase
Potential difference；
(4) other end of second radio-frequency cable component is trimmed, trimming coefficient is D:
3 be dielectric constant；360 indicate 360 degree of circumference；F indicates frequency；E indicates repair constant, is 2 when single channel, bilateral
It is 1 when road；L indicates physical length；VP indicates transmission speed, general value 84%；
(5) trimming length Cmm, C=D* phase difference are calculated；
(6) step (2)~(5) are repeated, assembly, test, the trimming of other radio-frequency cable components are completed.Wherein, step
In second radio-frequency cable component become N (N be greater than 2) root radio-frequency cable component.Such as make N (N is greater than 2) root radio-frequency cable
When component: production nth root radio-frequency cable component, one end of nth root radio-frequency cable component and upper (N-1 root) radio-frequency cable
Component is matched by connector device；By vector network analyzer carry out single channel test, and with first radio-frequency cable component pair
Than obtaining phase difference；The other end of nth root radio-frequency cable component is trimmed, trimming coefficient is D (calculation formula is as above), and calculating is repaired
Cut length Cmm, C=D* phase difference.
After radio-frequency cable component trimming, tested by vector network analyzer, and tested with benchmark CA cable assembly phase bit comparison
Card.
The method of the present invention combines the processing and measuring technology of current radio-frequency cable component, effective to guarantee inter-module phase one
Cause property, the matched qualification rate of phase equalization are maintained at 80% or more, are conducive to batch production.
Specific embodiment
The technical requirements of certain type radio-frequency cable component are as follows:
1) radio-frequency cable component length is 100mm；
