GSM frequency band filter structure is big in the existing machine system, and indoor design is complicated, processing difficulties, and debugging speed is slow, and power capacity is little, has become to use wireless communications products major obstacle in this GSM signal frequency range.
Therefore imagination provides a kind of GSM compact filter, is mainly used in the interior transmission signals of mobile communication base station machine system accessory GSM frequency range and uses filtering device.Adopting little appearance structure design, high power resonant vibration capacitor design is main feature; Its maximum external form length of GSM compact filter is no more than 110mm; Use the high-power minor structure filter of this GSM signal, the appearance structure that has not only reduced machine system has also enlarged the internal capacity of mobile base station.GSM compact filter has two ports are connected to whole set equipment respectively through feeder line other signal processing module.
Summary of the invention:
The object of the invention just provides a kind of GSM compact filter, is mainly used in the interior transmission signals of mobile communication base station machine system accessory GSM frequency range and uses filtering device.
The technical scheme that the present invention adopts is:
A kind of GSM compact filter; Comprise box body: box body inside has resonant cavity; The resonant cavity inwall is silver-plated; Be provided with some installing holes around the resonant cavity, some GSM signal high power resonant vibration electric capacity control levers are installed in the resonant cavity, be equipped with between GSM signal high power resonant vibration electric capacity control lever that the far-end band suppresses control elements outward and the near-end band suppresses control elements outward; The box body side is equipped with signal input port SMA-KFD type port connector; The box body side also is equipped with signal output port SMA-KFD type connector, and said signal input port SMA-KFD type port connector, signal output port SMA-KFD type connector all are connected to GSM signal high power resonant vibration electric capacity control lever through signal input, output transmission line; Cartridge upper surface is provided with cover plate, has some through holes on the cover plate and matches with GSM signal high power resonant vibration electric capacity control lever, also is provided with some holes that install and fix on the cover plate and matches with the interior installing hole of box body.
Its features of shape of said resonant cavity does, resonant cavity left-hand component is " 1 " font, and right-hand component is " own " font, and about the part top link to each other, said GSM signal high power resonant vibration electric capacity control lever is distributed in the resonant cavity mutually across a certain distance.
Compared with prior art, beneficial effect of the present invention is:
It is main feature that the present invention adopts little appearance structure design, high power resonant vibration capacitor design; Its maximum external form length is no more than 110mm; Use this GSM compact filter, the appearance structure that has not only reduced machine system has also enlarged the internal capacity of mobile base station.It has two ports are connected to whole set equipment respectively through feeder line other signal processing module.Owing to be that the long-term use of high power resonant vibration capacitor design is not fragile, also have two mounting grooves designs, plurality of advantages such as fastening are installed.
Description of drawings:
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is a covering plate structure sketch map of the present invention.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is done further explain through embodiment:
A kind of GSM compact filter; Comprise box body 1: box body 1 inside has resonant cavity 2; Resonant cavity 2 inwalls are silver-plated; Be provided with some installing holes 3 around the resonant cavity 2, some GSM signal high power resonant vibration electric capacity control levers 4 are installed in the resonant cavity 2,4 of GSM signal high power resonant vibration electric capacity control levers are equipped with the far-end band to be suppressed control elements 5 outward and suppresses control elements 6 outward with the near-end band; Box body 1 side is equipped with signal input port SMA-KFD type port connector 7; Box body 1 side also is equipped with signal output port SMA-KFD type connector 8, and said signal input port SMA-KFD type port connector 7, signal output port SMA-KFD type connector 8 all are connected to GSM signal high power resonant vibration electric capacity control lever 4 through signal input, output transmission line 9; Box body 1 upper surface is provided with cover plate 10; Have some through holes 11 on the cover plate 10 and match with GSM signal high power resonant vibration electric capacity control lever 4, also be provided with some holes 12 that install and fix on the cover plate 10 and match with the interior installing hole 3 of box body, resonant cavity 2 its features of shape do; Resonant cavity 2 left-hand components are " 1 " font; Right-hand component is " own " font, and about the part top link to each other, GSM signal high power resonant vibration electric capacity control lever 4 is distributed in the resonant cavity 2 mutually across a certain distance.
As shown in the figure it comprise resonant cavity.Resonant cavity mainly is used for transmitting signal curve and the needed technical indicator of product each item that the effect of intercoupling between each resonant capacitance is produced, and is a kind of microwave signal transmission line, and electric energy that is produced when powering up work and magnetic energy are stored at inside, chamber.Aerial lug spare is signal input, output port SMA-KFD type port connector; Be mainly used in feeder line (just connecting a transfer wire between the complete machine module) and connect mobile base station inner module and GSM compact filter, and GSM signal high power resonant vibration electric capacity control lever; Intra is designed with moulding and silver coating; The far-end band suppresses control elements outward; The near-end band (for example: unwanted frequency and index suppresses control elements outward; Can suppress long its size of control elements change by near-end and far-end realize), signal input, output transmission line (being used for being connected of intra and outside SMA-KFD type connector), cover plate.The GSM compact filter that mainly combines by this eight big core technology component.
