Description
Technical field
The utility model relates to the mobile communication technology field, relates in particular to a kind of base station signal amplification system.
Background technology
The develop rapidly of mobile communication cause has brought the continuous increase of mobile communication subscriber amount, on the one hand, along with the high stratification of urban construction, skyscraper just continues to bring out, owing to the shadow effect of radio transmission, often form the blind area of mobile communication signal in the behind of these skyscrapers.On the other hand, because rural area physical features complexity is wide, overhead mode is often adopted in the base station, has not only caused the cost of base station construction to increase, and the overhead signal transmission attenuation that can cause later of antenna strengthens the coverage decline of signal.This shows that increasing the area coverage of signal and intensity becomes and press for.The base station signal receive-transmit system of prior art as shown in Figure 1, this system mainly comprises up receiving unit, downlink part and base transceiver station, wherein up receiving unit mainly comprises up input filter, numerical-control attenuator, up output filter, and they are connected to base transceiver station successively from up reception antenna; The downlink part mainly comprises duplexer, coupler, descending input filter, numerical-control attenuator, descending output filter, and they are connected to the downlink antenna successively from base transceiver station; The numerical-control attenuator of ascender all is connected with supervising device with the numerical-control attenuator of descender.The weak strength of this system's receiving and transmitting signal, coverage is little.Some businessmans have been connected in series a power amplifier in order to improve up receiving sensitivity between up input filter and numerical-control attenuator, but have ignored the coverage effect of downlink signal, do not make the up-downgoing balance reach perfect effect.
The utility model content
At prior art system receiving and transmitting signal weak strength, coverage is little, do not reach the deficiency of up-downgoing balance, technical problem to be solved in the utility model is: provide a kind of signal strength signal intensity height, coverage big and can satisfy the base station signal amplification system of up-downgoing balance.
The technical scheme that its technical problem of solving the utility model adopts is: this base station signal amplification system mainly comprises the descending output filter and the numerical-control attenuator of the up input filter of supervising device, up receiving unit and numerical-control attenuator, downlink part, and up receiving unit all is connected with supervising device with the numerical-control attenuator of downlink part; This system also comprises DC power supply and two power amplifiers, one of them power amplifier is serially connected between the up input filter and numerical-control attenuator of up receiving unit, and another power amplifier is serially connected between the descending output filter and numerical-control attenuator of downlink part; Two power amplifiers all are connected with described DC power supply.
Described two power amplifiers all are connected with supervising device.
Each hard by-pass switch in parallel of described two power amplifiers.
The beneficial effects of the utility model are: this system's receiving and transmitting signal intensity height, signal cover are big, and can satisfy the up-downgoing balance.
Description of drawings
Fig. 1 is the block diagram of the base station signal receive-transmit system of prior art;
Fig. 2 is the block diagram of the utility model embodiment.
K is hard by-pass switch among the figure.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
The difference of the base station transceiver system of the utility model and prior art is: increased a DC power supply and two power amplifiers, one of them power amplifier is serially connected between the up input filter and numerical-control attenuator of up receiving unit, another power amplifier is serially connected between the descending output filter and numerical-control attenuator of downlink part, and DC power supply is two power amplifier power supplies.
Embodiment:
As shown in Figure 2, the base station signal amplification system in this example mainly comprises up receiving unit, downlink part, base transceiver station and supervising device.Wherein up receiving unit comprises up input filter, power amplifier, numerical-control attenuator, up output filter, and they are connected to base transceiver station successively from up reception antenna, is parallel with hard by-pass switch K on the power amplifier; Downlink partly comprises duplexer, coupler, descending input filter, numerical-control attenuator, power amplifier, descending output filter, and they are connected to the downlink antenna successively from base transceiver station, is parallel with hard by-pass switch K on the power amplifier.Up receiving unit all is connected with supervising device with two numerical-control attenuators with two power amplifiers of downlink part.
The signal that sends from mobile communication subscriber is transferred to up input filter through up reception antenna, filtered signal is transferred to power amplifier again and realizes that upward signal amplifies, and signal is sent to base transceiver station by numerical-control attenuator and up output filter more afterwards.A series of processing through base transceiver station, send the duplexer of downlink part to, the effect of duplexer is that uplink and downlink signals is separated, and the downstream signal of separating is transferred to power amplifier through coupler, descending input filter, numerical-control attenuator and realizes that downstream signal amplifies.The downstream signal of Fang Daing is sent to descending output filter and carries out filtering then, goes out via the downlink antenna transmission at last.Respectively be parallel with a hard by-pass switch K on two power amplifiers, its effect is, when power amplifier broke down, automatically hard bypass guaranteed the uninterrupted of base station communication, and DC power supply is two power amplifiers power supplies.Two numerical-control attenuators and two power amplifiers of up receiving unit and downlink part all are connected on the supervising device, so just can be to the working state real-time monitoring of numerical-control attenuator and power amplifier.
The utility model has not only solved the problem of receiving signal sensitivity difference, has also strengthened coverage and the intensity that transmits simultaneously, reaches the up-downgoing coupling.
