Description
Technical field
The utility model relates to a kind of communication coupler, relates in particular to a kind of broadband coupled device.
Background technology
Coaxial 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, and microwave signal is distributed in specific proportions or synthetic power, is one of element commonly used in the microwave technical field, occurs mainly with coaxial configuration.Being generally at main transmission line increases by the parts for coupling output, thereby realizes that distributing specific power from main transmission line exports from the another port.Because its structure is similar with principle also coupler, generally also can regard the coupler that does not have isolation as, the pass that defines equally between input power and the coupling power output is the degree of coupling.The characteristics of coaxial coupler be simple in structure, load power is big, intermodulation is low.
Present common coaxial coupler, 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.Be subjected to the restriction of coaxial outer conductor internal diameter size, coupled zone length is generally shorter, directly causes degree of coupling big rise and fall when realizing wideband or super wideband; As bandwidth of operation be 800MHZ～2500MHZ-coaxial coupler of 5DB, its coupling rise and fall-4.2DB～-5.8DB; And simultaneously for to guarantee that input port has littler standing-wave ratio in wideband or super wideband Time Bandwidth, needing to add matching unit, this matching unit is subjected to the impact 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 provides a kind of frequency range can realize 4 times or higher sound interval for the deficiencies in the prior art, and realizes that easily input port hangs down standing-wave ratio, low intermodulation, the coaxial coupler that low coupling rises and falls.
The utility model is achieved through the following technical solutions:
A kind of coaxial coupler, comprise main coaxial inner conductor and outer conductor, coupling output inner wire and outer conductor, main coaxial inner conductor is connected with the ring-type tetrafluoro of coupling output inner wire by signal coupling conductor and signal coupling conductor inside, described signal coupling conductor is the hollow cylinder with the same axis of main coaxial inner conductor, and coupling output inner wire crosses with the signal coupling conductor dbus that bolt is vertical to be connected.
A kind of coaxial coupler, described coupling output inner wire and signal coupling conductors junction are provided with bulge loop in the signal coupling conductors outside.
The signal coupling conductor is parallel with main line in the utility model coaxial coupler, so can require to select arbitrarily its length according to bandwidth and degree of coupling fluctuating, namely coupled zone length because coupling regime is longer, can realize littler coupling fluctuating in wider bandwidth; Different degree of coupling demands can be by adjusting internal diameter and the external diameter of hollow metal cylinder in the signal coupling conductor, and the diameter of main coaxial line part in coupling device is realized; Adjust the degree of coupling by the length of adjusting the signal coupling conductor and rise and fall, realize the fine setting that the degree of coupling rises and falls by adjusting near body diameter and the length of the main coaxial inner conductor signal coupling conductor; In the degree of coupling and the definite rear diameter of different cylinders in the main transmission line and low standing-wave ratio that length realizes input port adjusted that rise and fall.Coupling output inner wire and signal coupling conductor connection are provided with bulge loop in the signal coupling conductor outside and can reinforce coupling output inner wire and signal coupling conductor connection, also can play the effect of regulating index simultaneously.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.
