Description
Technical field
The invention belongs to mobile communication equipment field, particularly a kind of wide-band four enters four and goes out electric bridge; The present invention is carried out the synthetic of settling signal and is distributed by built-in coupling piece and contiguous block, mainly realize unlike signal path by coupling piece and contiguous block, wherein utilize the thickness of spacing control medium to ensure the spacing between coupling piece, thereby realize, signal distributes according to distribution ratio and the function of composite signal.
Background technology
Wideband electrical bridge is a kind of signal combiner device of the wireless telecommunications system that meets wide-band, is mainly used in realizing in the isolation of multiple homogenous frequency signals or the system of public many antennas.Single four enter four goes out the multipotency of electric bridge and realizes the signal input of four frequency bands and the signal output of four frequency ranges, reach with minimum loss, and optimum matching performance, four isolation indexs with frequency system the bests complete the networking of communication.
Along with the fast development of communication system diversification, from the construction of 2G, 3G standard type mobile communication systematic large-scale, to the commercial 4G standard LTE system type by Large scale construction.In increasing mobile communication system standard, the inside and outside electronic environment of each system type of complication system affects more and more serious, system group network construction cost and cycle are also more and more subject to the harsh requirement of various aspects, not only need to take into account multiple types compatibility, also need the system requirements such as reserved upgrading, networking optimization, dilatation, these have improved the networking requirement to communication network all extremely urgently:
A. it is synthetic and distribute 6 ± 0.7 dB that working band need to be realized the optimum of signal of 698-2700MHz;
B. passive system standard internal interference is enough low, and requiring has better intermodulation index, as need to meet≤-150dBc of third order intermodulation;
C. the lifting of system power capacity, requiring needs better matching performance, to avoid the impact of energy to emission system, requires standing-wave ratio (VSWR)≤1.2;
D. how individual high with degree of inhibition between the system type requirement system of frequency or concurrent, with frequency interport isolation index >=23dB;
E. the load power of multisystem standard, causes the lifting of the born power capacity of the passive device using in system to reach 300W;
F. many input ports and multiple output port, public one or more antenna-feedback system covers and dilatation, requires the passive device of power division to have input/output port as much as possible;
G. being convenient to Practical is connected with cable.Both can independently use, and can build again more complicated system and use, multiple ports are inputted with side direction, and multiple ports are exported with side direction, are convenient to project installation and are connected with cable.
In engineering in order to meet above-mentioned requirements, normal adopt four the two 3dB electric bridges that enter scene 2 to add that cable-assembly realizes four and enter four systemic-functions that go out electric bridge, shown in four Fig. 1 of normal employing two enter scene 2 electric bridge, connect by radio frequency cable or adapter, the multichannel input-output system that export on four tunnels is inputted on four tunnels that have that form Fig. 2 a, Fig. 2 b structure, four enter four and go out bridge system, can substantially meet like this engineering demand, but in practical implementation, have following problem in principle:
