Description
Technical field
The utility model relates to employed power coupler in the microwave technical field such as a kind of communication, radar.
Background technology
Coaxial power coupler is similar to the power divider of do not have isolating, and also can regard a kind of of five equilibrium two power dividers not as.It is mainly used in microwave signal by special ratios coupling or synthesize power, is one of element commonly used in the microwave technical field, how to occur with coaxial configuration.Being generally on main transmission line increases by one and is used to the parts of output that are coupled, thereby realizes that distributing specific power from main transmission line exports from the another port, and input power is the degree of coupling with the pass that is coupled between the power output.The characteristics of coaxial power coupler be simple in structure, load power is big, intermodulation is low.The coaxial power coupler of the coaxial configuration of the at present common big degree of coupling, the typical structure of its coupling unit is that a hollow cylinder vertical with main line is set, and controls the degree of coupling by control hollow cylinder internal diameter size.The fault of construction of coupling regime causes degree of coupling big rise and fall when realizing wideband or super wideband; As bandwidth of operation be 800MHZ～2500MHZ-coaxial power coupler of 5DB, its coupling rise and fall-4.2DB～-5.8DB; And, needing to add matching unit simultaneously for to guarantee that input port has less standing-wave ratio in wideband or super wideband Time Bandwidth, this matching unit is subjected to the influence of coupling regime.Because the coupled zone length of this structure is short and more fixing, want to realize that more wideband application and littler coupling rise and fall very difficult.
The utility model content
The utility model has been designed and developed out frequency range and can have been realized 4 times or higher sound interval at the deficiencies in the prior art, and is easy to realize that input port hangs down standing-wave ratio, low intermodulation, and when the degree of coupling is bigger, the coaxial power coupler that the coupling fluctuating is low.
The utility model is achieved through the following technical solutions:
A kind of coaxial power coupler comprises port connector, main coaxial inner conductor and outer conductor, and coupling output inner wire and outer conductor, described coupling device is suspended on the main coaxial inner conductor.
A kind of coaxial power coupler, described coupling device comprise the metal tubbiness cylinder vertical with main transmission line, reach the ring-type tetrafluoro that fixation is played in metal tubbiness cylinder top; Coupling output inner wire closely cooperates with air cylinder insulator and is connected with the bottom surface of metal tubbiness cylinder.
Advantage of the present utility model and effect are:
Coupling device vertically is suspended on the main transmission line, can change the distance of coupling unit and main coaxial line according to the bandwidth needs, controls by the different-diameter of coupling outer conductor, thereby realizes that in broadband less coupling rises and falls.In assembling process, also avoided simultaneously because the coupling device that size causes and the phenomenon of outer conductor short circuit.
Description of drawings
Accompanying drawing is the sectional structure schematic diagram.
Embodiment
Shown in accompanying drawing.
The utility model coupling device is suspended on the main coaxial inner conductor 401.Coupling device is by form main coaxial inner conductor 401, coupled end output inner wire 402, ring-type tetrafluoro 403, metal tubbiness cylinder 404 with the lower part.Implementation process: the concentric column that main coaxial inner conductor 401 is a plurality of different-diameter different lengths is formed, in order to guarantee machining accuracy and to provide easy to process.And the easy assembling in assembling process, main coaxial inner conductor 401 can be divided into more piece, middle form with screw thread is connected.This implementation process is divided into two parts with the coupling device in the cavity.At first main coaxial inner conductor is installed in the main coaxial outer conductor, two ports of this coupling device of connecting are installed two coaxial connectors 411,412.Begin to assemble coupled end then, at first ring-type tetrafluoro 403 is installed on the coupled end output inner wire 402, tight fit between the two, then both are connected with the bottom of metal tubbiness cylinder 404 with the form of screw thread, the degree of depth of metal tubbiness cylinder equals the thickness that the thinner length that saves of coupled end output inner wire deducts insulator, forms closely between the three to connect.The radius of insulator is greater than the radius of metal tubbiness cylinder.The coupling device that connects is installed on the coupling output outer conductor, air chamber in the outer conductor, it is the different cylinder of radius, the diameter of big slightly air cylinder and insulator measure-alike, coupling device can be installed on the outer conductor like this,, can change the position of coupling device at outer conductor by the height of the less air cylinder of Control Radius, thereby changed the distance between coupling device and the main coaxial line, changed the degree of coupling.With coupling device and the outer conductor that connects, be installed on the main coaxial outer conductor, between the two by being threaded.Owing to rock the displacement of generation, above mounted coupling device, increase a hollow metal cylinder 405 for coupling device, then the other end of coaxial connector 413 with the coupled end inner wire is connected by screw thread.A face of hollow cylinder contacts with the insulator cross section, and the another one face contacts with coaxial connector, can locate firmly like this, can not become flexible.
Coupling device is vertical with main line in the utility model coaxial power coupler, so can require to select arbitrarily its length, i.e. distance between coupled zone length, and coupling device and the main coaxial inner conductor according to bandwidth and degree of coupling fluctuating; Different degree of coupling demands can realize by the length of adjusting the different-diameter air cylinder of secondary coaxial outer conductor in the coupling device; Adjust the degree of coupling by the length of adjusting coupling device and rise and fall, realize the fine setting that the degree of coupling rises and falls by adjusting near the body diameter and the length of main coaxial inner conductor 401 coupling device; Adjust the diameter of different cylinders in the main transmission line and the low standing-wave ratio that length realizes input port in the degree of coupling and definite back that rises and falls.The utility model is simple in structure, firmly, the distortion that should not be moved in the use, easy to process, the low standing-wave ratio of input port in broadband, coupling rises and falls little, low intermodulation.
