Description
Technical field
The utility model relates to microwave device technical field more particularly to a kind of microwave ferrite circulator isolator are inclined
Set magnetic field debugging structure.
Background technique
Component, component, component, the miniaturization of system, work reliability be direction and the research of electronic technology development
Target, in microwave system be realization system the operation is stable, smoothly complete the transmitting-receiving of signal, largely using isolator, go in ring
Device.Isolator, circulator are indispensable key components in microwave system.
Isolator, circulator belong to Microwave Iron Oxide Elements.The ferrite gyromagnetic material that it is used is in external high-frequency wave field
With under the collective effect of stationary magnetic field generate tensor permeability characteristic, and make the electromagnetic wave propagated in ferrite occur it is polarized
Rotation, to produce isolator, circulator.Therefore every electrical performance indexes of isolator, circulator are by the big of externally-applied magnetic field
It is small and uniformity to be affected.
The size and uniformity of isolator, circulator bias magnetic field, by assembly during manufacturing and raw material etc.
It influences, there are notable differences for the size and uniformity of every product bias magnetic field, since the quality of bias magnetic field is to product electrical property
Energy is affected, so needing to debug bias magnetic field.
Isolator, circulator bias magnetic field debugging technique research in terms of, at present generally by control raw material and
Assembling quality improves the consistency and qualification rate of externally-applied magnetic field, due to only one lid of current isolator/circulator cover board
Plate, effect are only the components for compressing and placing in the cavity, so generally requiring to begin to speak to carry out magnetic field repeatedly in debugging
Repeatedly debugging, and repeat to begin to speak that not only heavy workload, production efficiency are lower, and can also introduce other uncontrollable factors leads to product
Reliability reduce, or even failure, especially in the case where magnetic field itself needed for product is weaker, it is more difficult to control.
Summary of the invention
The purpose of this utility model, in that a kind of microwave ferrite circulator isolator bias magnetic field debugging knot is provided

Wave system is united the requirement of integral miniaturization, is not often in this way optimal structure, and sub- cover board is too thick will increase device entirety
Weight, while the too thick sensitivity level to flux control of its thickness also can decrease.
As a preferred technical scheme: being provided at least two through-holes on the sub- cover board.Through-hole is set, work can be used
In tool insertion through-hole, to keep sub- cover board rotation more convenient.
As further preferred technical solution: the through-hole is two, and is symmetrical arranged on the sub- cover board.Technique
Simply, and rotation be more convenient it is more labor-saving.
As a preferred technical scheme: the cavity, sub- cover board and female cover board use high permeability material.More conducively constitute envelope
Close magnetic loop.
As further preferred technical solution: the high permeability material is ingot iron material or A3 steel.
The utility model also provides a kind of method for being biased magnetic field debugging using above-mentioned debugging structure, the skill of use
Art scheme is, comprising the following steps:
(1) by screwing sub- cover board, so as to adjust the height of sub- cover board, to debug intracavitary magnetic field；
(2) after debugging, in female cover board and cavity junction, female cover board and sub- cover board junction gluing, make female cover board,

(1) isolator/circulator magnetic field adjustment accuracy and efficiency can be effectively improved；It is single compared with tradition begins to speak debugging
The debug time of device shortens 70% or more, can greatly improve debugging efficiency, reduces production cost；Tune of uncapping is reduced simultaneously
Examination, greatly improves the reliability of product；
(2) it can avoid beginning to speak to debug the risk that magnetic field causes isolator/circulator reliability to reduce or fail repeatedly, solution
Debug problem in the magnetic field that Integral double cavity of having determined designs the opposite circulator isolator assemblies in direction of rotation；Tradition is begun to speak debugger
The crash rate of part is 15% or so, crash rate can be reduced to 5% or less using this adjustment method.Tradition, which begins to speak to debug, is equivalent to weight
New clothes are matched, and may be positioned because of assembly, be brought the reliability of the factors such as foreign matter, circuit modifications reduction product into, and use this primary and secondary
The consistency of lid adjustment method, product is higher, will not introduce remaining uncontrollable factor because beginning to speak repeatedly；
(3) magnetic field debugging facilitates accurate, simplifies isolator/circulator production technology.
