Description
Technical field：
The present invention relates to a kind of integral type multi-system access platforms.
Background technology：
Currently, using the cascade scheme of electric bridge, scheme as shown in Figure 2, according to input for traditional multi-system access platform
Port number is cascaded a certain number of electric bridges (5) using coaxial cable (6), and needs to use coaxial load (7) will
Electric bridge（5）The port that sky is put terminates, by all signals through electric bridge（5）It carries out after synthesizing step by step, final output is traditional
Scheme mainly brings following drawback：One, index is unstable, due to the use of to electric bridge quantity it is relatively more, each electric bridge is all
The overall objective of product can be had an impact, and be attached using coaxial line between electric bridge and electric bridge, increase properties of product not
Stable probability；Two, noise is big, and since traditional scheme is all cascaded using electric bridge, electric bridge itself is without any filtering work(
Can, therefore when carrying out signal processing, any signal can be inputted and be exported, and cause the noise of whole system inclined
Greatly；Three, signal interference is big, and since traditional scheme is cascaded using electric bridge, the isolation strength of electric bridge is smaller, is carrying out signal
When processing, when especially being handled between homogenous frequency signal, easily there is a phenomenon where signal disorder, the clear of signal cannot achieve
Output；Four, loss is big, and traditional scheme is cascaded using electric bridge, and loss when single electric bridge is very big, and more cascade
Electric bridge overall losses bigger causes multisystem mixing platform entirety Insertion Loss bigger than normal, and power attenuation is larger, and extra port needs
It is terminated using coaxial load, causes signal when each grade carries out synthesis processing, there is the signal power quilt of most
Coaxial load is absorbed, and loss is very big, and when use needs to increase power amplifier in output end and could use.
Invention content：
To overcome the defect of traditional technical solution, that the purpose of the present invention is to provide a kind of intermodulation performances is good, simple in structure,
Debug the integral type multi-system access platform of convenience, performance stabilization, low-loss, big isolation, high-resolution；
The present invention solves technical problem and adopts the following technical scheme that：
A kind of integral type multi-system access platform, including：
Divide combiner unit, full range combiner unit, transmission unit.
It is characterized in that：
The frequency dividing combiner unit is mainly made of two frequency dividing combiners, and only company is arranged in input terminal in two frequency dividing combiners
Device is connect, connector is not set in output end；
The full range combiner unit is a kind of special electric bridge, which is only arranged connector in output end, is not set in input terminal
Set connector；
The transmission unit of the integral type multi-system access platform directly uses air transmission cavity that will divide using direct transmission theory
Frequency combiner unit is connected with full range combiner unit；
The integral type multi-system access platform will not only divide combiner unit, full range combiner unit, and transmission unit is designed as
Integral structure is realized integrated；And it can be simultaneously by the signal of the different systems of different operators in same equipment
Realization is handled, and realizes resource-sharing；
The low-loss of the integral type multi-system access platform may be implemented the low-loss of signal and pass through, effective to be promoted
The utilization rate of signal reduces the resource loss in signal processing.
Compared with the prior art, beneficial effects of the present invention are embodied in：
The integral type multi-system access platform of the present invention, benefit are mainly reflected in：One realizes resource-sharing, using integral type
Scheme, integrate frequency dividing combiner unit, full range combiner unit and transmission unit；The signal of different operators different systems is merged,
Realize the reception, processing and output of different systems signal simultaneously in same equipment；Secondly realizing the high-resolution of signal, adopt
Theory is filtered with signal, selective filter is carried out to signal, irrelevant signal or non-object signal are directly filtered, is ensured most
The all necessary signals of secondary synthesis signal exported eventually；Using signal isolation theory, isolation is used to the signal of different systems
Processing, realizes taking their own roads for signal, ensures to interfere with each other between the signal of different systems, realize the high-resolution of signal
Property；Thirdly being service efficiency height, low-loss Technology application reduces loss of the product to signal, realizes signal in the present invention
Low-loss in processing procedure, promotion signal service efficiency；It four is stronger index stability, such scheme it is more
System access platform carries out single sintering to the signal of different systems using frequency dividing combiner unit, is connect instead of traditional multisystem
Enter a fairly large number of electric bridge in platform, reduce parts usage quantity, promotes index stability；Transmission unit is realized straight in the wrong
It reads, realizes that the signal of frequency dividing combiner unit and full range combiner unit is directly defeated, it is more to substitute quantity in traditional multi-system access platform
Coaxial line, reduce parts usage quantity, promoted index stability.

Fig. 1 is design scheme schematic diagram of the present invention；Fig. 2 is traditional design scenario-frame schematic diagram；
Figure label：1 frequency dividing combiner unit, 2 full range combiner units, 3 transmission units, 4 connectors, 5 electric bridges, 6 coaxial cables, 7
Coaxial load；Below by way of specific implementation mode, and in conjunction with attached drawing 1, the invention will be further described.
Specific implementation mode：
Embodiment：In conjunction with Fig. 1, the integral type multi-system access platform of the present embodiment, including：
