Description
Technical field
The present invention relates to wireless mobile telecommunication technology technical fields, and in particular to a kind of integration multi-frequency and multi-system combining
Device.
Background technology
The past more than ten years are the ages of wireless mobile telecommunication technology rapid development, especially in China.In but due to
The frequency distribution of state's mobile communication has certain particularity, and many times not only needing wave filter and duplexer, these are common
Device products, it is also desirable to the product of some combiners.Combiner can include two-in-one, three-in-one, four-in-one, even more multichannel
Signal frequency merge into a single whole or be divided into integral combiner device.This combiner device product, which just proposes design, to be had more
The requirement of challenge.
At present, China Mobile's development is when be most hot, mobile communication frequency have broadcasting and TV TDV470-860MHz,
Telecommunications CDMA825-835/870-880, cluster 806-821/851-866MHZ, mobile GSM885-909/930-954MHz, unicom
GSM909-915/954-960MHz, mobile DCS1710-1730/1805-1825MHz, unicom DCS1740-1755/1835-
1850MHz, mobile 3G and LTE2010-2025/1880-1920/2300-2400/2570-2620MHz, unicom 3G and
LTE1940-1955/2130-2145/1755-1785/1850-1880MHz, telecommunications 3G and LTE825-835/870-880/
1920-1935/2110-2125/2540-2640MHz, the frequency of unicom mobile communication wireless network are 2400-2483.5MHz etc.
System, when each system is used alone, typically using duplexer, for example, pervious base station and it is dry put, present RRU (refers to
Be present base station) front end is all the duplexer used.
However, due to the natural weakness of wireless communication, the distribution of signal indoors suffers from the stop of building and produces
Raw many dead angles, especially this phenomenon is more serious in some buildings.Some difficult, indoor distributions in order to overcome this
System extends indoors as entire wireless communication system to be widely used.But if to need one by a frequency band
Indoor distributed system is covered to cover, it is necessary to which many indoor distributed systems are existed simultaneously and could thoroughly solved the problems, such as, such
Scheme is the beauty destroyed in building, and increases cost, thus multi-frequency and multi-system combiner is widely used.
Signals more than five or more or more frequencies, is exactly integrated in one by so-called integration multi-frequency and multi-system combiner
Play the same indoor distributed system of share.Under normal circumstances, it is not that two sub- frequency divisions of reception and transmitting is needed to open.This
The problem of sample is that the isolation between each frequency is just not necessarily made very high, for example unicom 3G and telecommunications 3G frequencies are separated by only 5MHz,
Its mutual isolation is difficult to accomplish to be satisfied with.In order to solve the problems, such as this, one of which scheme is exactly that uplink and downlink is separately set
Meter.In this way, since the band width of each passband is relatively narrow, mutual isolation is also just more easy to implement than in the past, so
Since, four five in one originally reform into more than ten present unifications or one point of more than ten combiner device.
At present, multi-frequency and multi-system combiner is formed by multiple filter banks, and the coupling disc of logical transmission line end
It is all being held jointly to adjust port time delay to reach the signal of the different frequencies of wave filter with the air capacitance spacing of common male end resonator
Mouth reaches the port match time delay of design requirement, but its construction is complicated, and cost of manufacture is high, is not easy to produce in batches, moreover,
Multi-frequency and multi-system combiner is all welded using more tap lines, at most also just accomplishes 7 frequency combiners, and port time delay is difficult
Matching, debugging difficulty are not easy to produce in batches greatly, and also difficulty reaches requirement to index, it is suppressed that integrated multi-frequency and multi-system combiner
It is fast-developing.
