Description
Technical field
The utility model relates to communication equipment field, particularly relates to a kind of signal coupling and closes road device.
Background technology
At present, many signal couplings in communication equipment, close road function and divide two kinds of forms, one is homogenous frequency signal, adopts coupler coupling, and recycling power splitter closes road, obtains multiple signals He road signal.As shown in Figure 1, Fig. 1 is that prior art is closed road mode with the coupling of different carrier signal frequently, comprise two paths of signals, signal a and signal b, signal a utilizes coaxial rod to carry out primary path input and primary path output, and signal b utilizes another coaxial rod to carry out primary path input and primary path output, wherein, two coaxial rods lay respectively in different coaxial cavities, and between signal, primary path is separate.When signal is in transmitting procedure, with the coupling line of coaxial rod in same coaxial cavity, signal is coupled, the two paths of signals being coupled out closes road output via power splitter.This mode is the in the situation that of same communications band different carrier signal, and to use power splitter to close road consistent with alien frequencies signal, and when 2 road signals close road, signal power reduces by half, and power reduces 3dB; When 4 road signals close road, signal attenuation is greater than 6dB; When 6 road signals close road, decay is greater than 8dB; When 8 road signals close road, decay is greater than 9dB.Determining close road output signal power in the situation that, the coupling of Gai He road mode is along with the increase of input signal quantity, the corresponding increase of the degree of coupling.
The second is alien frequencies signal, adopts the coupler different frequency range signal that is first coupled, then by mixer, unlike signal is closed to road, obtains many signals He road signal.As shown in Figure 2, Fig. 2 is that road mode is closed in the coupling of prior art alien frequencies signal, comprise two paths of signals, signal c and signal d, signal c utilizes coaxial rod to carry out primary path input and primary path output, and signal d utilizes another coaxial rod to carry out primary path input and primary path output, wherein, two coaxial rods lay respectively in different coaxial cavities, and between signal, primary path is separate.When signal is in transmitting procedure, with the coupling line of coaxial rod in same coaxial cavity, signal is coupled, the two paths of signals being coupled out closes road output via mixer.Ci He road mode loss of signal depends on mixer insertion loss, and general insertion loss is 1dB left and right, decays to 1dB left and right so every road coupled signal closes road.
In actual applications, be generally He road between same communications band different carrier signal.The in the situation that in current mobile communication, RF hopping technology generally being used, carrier frequency is at any time in saltus step, utilize mixer to close road to narrowband carrier signal impossible, therefore can only adopt the form of power splitter to close road, incoming carrier is more, and the distribution attenuation loss of power splitter is larger, after greatly to a certain extent, distribute decay to make to close road signal and cannot meet actual requirement, in actual use, cannot realize and close road.In the time that alien frequencies segment signal is inputted, need to select suitable mixer, when input signal quantity becomes 5 or more when multichannel, it is quite complicated that mixer just becomes, and even cannot use mixer to realize and close road.

Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Refer to Fig. 3, Fig. 3 is the schematic diagram that the utility model signal coupling closes road device one embodiment.In the present embodiment, signal coupling closes road device and comprises some coaxial rods, closes route and coaxial cavity.
Wherein, some coaxial rods are respectively used to transmit unlike signal.Close route for the signal of the some coaxial rods of capacitive coupling and close road.
Wherein, some coaxial rods close route with coupling respectively and be arranged in parallel, and coaxial rod and coupling are closed route and be all installed in same coaxial cavity.
In the present embodiment, the set-up mode that closes route comprises following two kinds of modes.
A. close route and be the setting of square-wave pulse shape based on an illusory face, form coupling branch line side by side some and that be parallel to each other, between adjacent two coupling branch lines, have connecting line, each coaxial rod and a coupling branch line are set in parallel.
B. close route comprise some side by side, be parallel to each other and be positioned at the coupling branch line of different illusory, and connect some connecting lines of adjacent two coupling branch lines, each coaxial rod is set in parallel with the branch line that is coupled.
Wherein, the present embodiment arranges and closes route in A mode.Be specially, coaxial cavity any side in coaxial rod place adopts the mode of fluting to get coupling, and the fluting face that closes route is positioned at the same plane of coaxial cavity, can make all coupling branch lines in identical horizontal plane, be convenient to realize and close road, reduce design difficulty.
In the present embodiment, coaxial rod and the both sides of closing route and be installed in respectively same coaxial cavity.Coaxial cavity in the present embodiment is cuboid.
In other embodiments, coaxial cavity also can be other shapes, as cylinder etc.
In the present embodiment, coaxial rod is realized the signal transmission of primary path, the corresponding primary path of a coaxial rod, and this mode can make to keep higher isolation between primary path, reduces the impact between primary path, and its passive intermodulation impact each other can be ignored.

In the present embodiment, the signal of coaxial rod transmission is with frequency in-phase signal, with frequency different carrier signal or alien frequencies signal.
The present embodiment can be realized the coupling of multichannel unlike signal and close road, is specially many primary paths signal and closes route coupling, closes behind road through overcoupling, closes road signal from the output output of closing route.
Above-mentioned implementation can be divided into two processes, and coupling process is passed by journey with closing, and below two processes is described in detail.
Coupling process is similar to common coupler coupling, high-power signal is from the input of primary path input e end, from the output of primary path output e end, correspondingly, the present embodiment has multiple consistent input～output primary paths, signal path can be inputted x～primary path output x up to primary path and finish, and x represents infinite herein.All input～output primary paths are consistent with input e～output e primary path way of realization, but separate with input e～output e primary path, and are mutually independent between all primary paths.Separate signal primary path, adopts the mode of coaxial rod to realize.
The input signal of each primary path can be with frequency in-phase signal, with frequency different carrier signal or alien frequencies signal.Utilization is closed route above-mentioned signal is coupled.
