Description
Technical field
The utility model relates to the Mobile communication direct base station field, particularly relates to digital RF far-drawing system.
Background technology
Along with the fast development of mobile communication cause, radio network optimization and the network coverage and have day by day shown its importance.Wherein, because direct discharging station has that cost of investment is low, rapid networking and rapid increase coverage territory, in radio network optimization and covering, become an indispensable part.
Follow the develop rapidly of mobile communication cause, each common carrier requires also in further raising for the covering quality of mobile communications network, need to carry out the degree of depth in occasions such as intensive market, residential quarter, university cities and cover.The mode of external antenna is adopted in traditional repeater, the waterproof and dampproof performance of antenna a little less than, disguise is not high.Simultaneously because the resident has very strong conflict consciousness to the radiation of wireless base station, there is the problem of property difficult coordination, selective calling difficulty.
The utility model content
Based on this, the utility model provides two kinds of digital RF far-drawing systems, and its remote termination and antenna possess beautifying property of height and highly concealed type, also possesses high waterproof and dampproof performance simultaneously.Can effectively solve the problem of property difficult coordination and selective calling difficulty.
A kind of digital RF far-drawing system comprises near-end machine, remote termination and antenna; Described near-end machine is connected with described remote termination; Described remote termination comprises digital RF monitoring integrated module, up LNA unit, duplexer, descending power amplifying unit; Described up LNA unit, described duplexer and the descending power amplifying unit of being connected connect successively; Described digital RF monitoring integrated module respectively with described up LNA unit be connected the descending power amplifying unit and be connected;
Wherein, also comprise casing, described antenna is installed in the described casing, is connected with described duplexer.
The utility model is installed in antenna in the casing, and the waterproof and dampproof performance of antenna strengthens greatly, and has highly concealed type; The utility model is in conjunction with the digital long-drawn technology and beautify type shot-light technology, and the aesthetic property of system is improved greatly, can be widely used in the occasions such as market, residential quarter, and practicality is very high.
Description of drawings
Fig. 1 is the utility model digital RF far-drawing system structural representation in one embodiment.
Fig. 2 is the utility model digital RF far-drawing system structural representation in another embodiment.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
As shown in Figure 1, be the utility model digital RF far-drawing system structural representation in one embodiment; This digital RF far-drawing system comprises near-end machine 10, remote termination 20 and antenna 30; Described near-end machine 10 is connected with described remote termination 20; Described remote termination 20 comprises digital RF monitoring integrated module 201, up LNA unit 202, duplexer 203, descending power amplifying unit 204;
Described up LNA unit 202, described duplexer 203 and the descending power amplifying unit 204 of being connected connect successively; Described digital RF monitoring integrated module 201 respectively with described up LNA unit 202 be connected descending power amplifying unit 204 and be connected;
Wherein, also comprise casing 205, described antenna 30 is installed in the described casing 205, is connected with described duplexer 203 by radio frequency cable;
In the present embodiment, described antenna 30 and described remote termination 20 all are installed in the described casing 205, and described antenna 30 is connected with described duplexer 203, antenna 30 and remote termination 20 integrated designs; The waterproof and dampproof performance of antenna 30 strengthens greatly, and has highly concealed type, beautifies degree and greatly improves;
Preferably, described casing is the torch-type distribution box.
As shown in Figure 2, the utility model digital RF far-drawing system structural representation in another embodiment, with the difference of above-described embodiment be that casing 205 is the shot-light lampshade, described antenna 30 is installed in the shot-light lampshade, is connected with described duplexer 203 by feeder line; The waterproof and dampproof performance of spotlight antenna is good, and has highly concealed type, and aesthetic measure further strengthens; During installation, remote termination 20 is affiliated in the back side or the bottom of shot-light lampshade 40 gets final product;
In the present embodiment, described remote termination also can comprise remote termination cabinet 206, and the remote termination cabinet can be the torch-type distribution box, can further beautify this digital RF far-drawing system.
The operation principle of the utility model digital RF far-drawing system is: near-end machine and remote termination all become received signal I/Q base band or Low Medium Frequency signal, then pass through A/D and Digital Signal Processing, form digital signal, transmission is therebetween adopted Optical Fiber Transmission by the digital fiber transceiver.Near-end direct-coupling base station signal enters downstream branch after diplexer separates, enter into digital RF monitoring integrated module, in this module, carry out down-conversion and carry out becoming baseband signal after the A/D conversion, after in digital signal processing module, carrying out the filtering processing, after it is packaged into the frame format that is fit to the CPRI interface requirement, send it to remote termination by digital fiber transceiver, optical fiber; Remote termination is sent baseband digital signal into baseband processing unit in the digital RF monitoring integrated module by the digital fiber transceiver, it is reverted to baseband signal, become analog signal through the D/A converter, be transformed to by the up-converter module in the digital RF monitoring integrated module and export the descending power amplifying unit to after the radiofrequency signal and carry out power amplification, pass through again duplexer filtering, at last by antenna transmission to user mobile phone.From the signal of portable terminal, receive by transferring to remote termination after the antenna acceptance, the inverse process by said process sends back the mobile communication base station again.
The utility model is installed in antenna in the casing, and the waterproof and dampproof performance of antenna strengthens greatly, and has highly concealed type; The utility model is in conjunction with the digital long-drawn technology and beautify type shot-light technology, and the aesthetic property of system is improved greatly, can be widely used in the occasions such as market, residential quarter, and practicality is very high.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
