Description
Technical field
The present invention relates to the power coupler used in the microwave technical field such as a kind of communication, radar.
Background technology
Coaxial power coupler, similar to the power divider of no isolation, also may be regarded as the one of not decile two power divider
Kind.It is mainly used in microwave signal and couples in specific proportions or synthesize power, is one of conventional element in microwave technical field,
Many occurred with coaxial configuration.One part being used for coupling output is generally increased on main transmission line, thus realizing from main transmission
Distribute specific power in line to export from another port, input power is the degree of coupling with the relation coupling between power output.
The feature of coaxial power coupler is that structure is simple, load power is big, mutually turns down.The coaxial knot of the larger degree of coupling common at present
The coaxial power coupler of structure, the typical structure of its coupling unit is setting one hollow cylinder vertical with main line, by controlling
Hollow cylinder internal diameter size is controlling the degree of coupling.The fault of construction of coupling regime leads to the degree of coupling when realizing wideband or ultra-wideband
Big rise and fall；As the coaxial power coupler of -5DB for 800MHZ～2500MHZ for the bandwidth of operation, its coupling fluctuating is in -4.2DB
～-5.8DB；And be to ensure that input port has less standing-wave ratio in wideband or ultra-wideband Time Bandwidth, coupling need to be added. simultaneously
Unit, this matching unit is affected by coupling regime.Because the coupling section length of this structure is shorter and compares fixation, want to realize
The application of more wideband and less coupling fluctuating are very difficult.
Content of the invention
What the present invention was directed to prior art is not to have designed and developed out frequency range and can achieve 4 times or higher frequency journey, and be easy to
Realize the low standing-wave ratio of input port, low intermodulation, when the degree of coupling is larger, couple the low coaxial power coupler that rises and falls.
The present invention is achieved by the following technical solutions：
A kind of coaxial power coupler, including port connector, main coaxial inner conductor and outer conductor, lead in coupling output
Body and outer conductor, described coupler is suspended on main coaxial inner conductor, above described coupler, increases a metal hollow
Cylinder, the one side of this hollow cylinder contacts with insulator cross section, and in addition one side contacts with coaxial connector.
A kind of coaxial power coupler, described coupler includes the metal tubbiness cylinder vertical with main transmission line and gold
Belong to the ring-type tetrafluoro playing fixation above tubbiness cylinder；Coupling output inner wire and air cylinder insulator be fitted close and with
The bottom surface of metal tubbiness cylinder is connected.
Advantages of the present invention and effect are：
Coupler suspended vertically on main transmission line, can according to bandwidth need to change coupling unit and main coaxial line away from
From, by couple outer conductor different-diameter control, thus realize in broadband less coupling rise and fall.In assembling process
In, it also avoid the phenomenon of coupler because size leads to and outer conductor short circuit simultaneously.Using hollow cylinder to coupler
Carry out spacing, coupler transport can be avoided to rock generation displacement, will not produce loosening.
Brief description
Accompanying drawing 1 is cross section structure diagram.
Specific embodiment
Referring to shown in accompanying drawing.
Coupler of the present invention is suspended on main coaxial inner conductor 401.Coupler is made up of following part, in main coaxial line
Conductor 401, coupled end exports inner wire 402, ring-type tetrafluoro 403, metal tubbiness cylinder 404.Implementation process：Lead in main coaxial line
Body 401 is the concentric column composition of multiple different-diameter different lengths, in order to ensure machining accuracy and provide easy to process.And
Main coaxial inner conductor 401 can be divided into more piece by the easy assembling in assembling process, middle connected in the form of screw thread
Connect.This implementation process, the coupler in cavity is divided into two parts.First main coaxial inner conductor is installed to main coaxial line
In outer conductor, two coaxial connectors 411,412 are installed in two ports of this coupler connecting.Then start to assemble coupling
Close end, ring-type tetrafluoro 403 is installed on coupled end output inner wire 402 first, tight fit between the two, then by both with spiral shell
The form of line is connected with the bottom of metal tubbiness cylinder 404, and the depth of metal tubbiness cylinder is equal to coupled end and exports inner wire
The length of a thinner section deducts the thickness of insulator, is formed and closely connect between three.The radius of insulator is more than metal drum
The radius of shape cylinder.The coupler connecting is arranged on coupling output outer conductor, air chamber in outer conductor, be radius not
With cylinder, the slightly larger diameter of air cylinder and insulator equivalently-sized, so coupler can be arranged on outer conductor
On, by the height of the less air cylinder of Control Radius, thus it is possible to vary coupler is in the position of outer conductor, thus changing coupling
The distance between clutch and main coaxial line, change the degree of coupling.By the coupler connecting and outer conductor, it is arranged on main coaxial line
On outer conductor, it is threaded connection between the two.In order to coupler is due to rocking the displacement of generation, on mounted coupler
Side, increases a hollow metal cylinder 405, then the other end of coaxial connector 413 and coupled end inner wire is passed through screw thread
It is connected.One face of hollow cylinder contacts with insulator cross section, and another one face contacts with coaxial connector, so permissible
Firmly position, will not loosen.
In coaxial power coupler of the present invention, coupler is vertical with main line, therefore can be risen and fallen according to bandwidth and the degree of coupling and require to appoint
Meaning selects its length, that is, couple section length, and the distance between coupler and main coaxial inner conductor；The different degrees of coupling needs
Ask, can be realized by adjusting the length of the different-diameter air cylinder of secondary coaxial outer conductor in coupler；By adjusting coupling
The length of clutch come to adjust the degree of coupling rise and fall, by adjust body diameter near coupler for the main coaxial inner conductor 401 with
Length come to realize the degree of coupling fluctuating fine setting；In adjustment main transmission line after the degree of coupling and rising and falling determines the diameter of different cylinders and
Length is realizing the low standing-wave ratio of input port.Present configuration is simple, Gu, should not be moved in use deformation, processing
Convenient, the low standing-wave ratio of input port in broadband, coupling little, the low intermodulation of fluctuating.
