Abstract
The invention discloses an AWS/PCS duplexer realized by bandpass and band stop. The AWS/PCS duplexer comprises a cavity and a cover plate, wherein a public port, a first port and a second port are formed in the cavity. The AWS/PCS duplexer is characterized in that a path of band stop filter and a path of bandpass filter are arranged in the cavity; the first port is connected with the band stop filter; the second port is connected with the bandpass filter. The AWS/PCS duplexer uses the bandpass and band stop mode, and thus the size is effectively reduced; the AWS/PCS duplexer can be realized only by two paths; the miniaturization of the duplexer is realized. In addition, the AWS/PCS duplexer has the advantages that the structure is simple; the processing and the debugging are convenient.
Description
Technical field
The invention belongs to electronic communication technology field, more particularly to a kind of band logical adds the AWS/PCS duplexs realized with resistance
Device.
Background technology
With the development of the communication technology, operator is less and less to the volume requirement of communication equipment, solves communication equipment body
The maximally effective method of product is the volume for reducing all parts in communication equipment, and radio-frequency front-end duplexer is often accounted in a communications device
There is sizable volume.
Current operator not only requires that the electrical performance indexes of duplexer are strict but also the volume to product also requires that miniaturization.
Existing AWS/PCS duplexers partial structurtes are as shown in figure 1, including cavity 11, port 12, resonant column 13.
The structure major defect of prior art shown in Fig. 1 is：1st, AWS/PCS duplexers are needed with No. three bandpass filter realities
Existing, volume is larger；2nd, product machining and debug time are long；These are all existing duplexer design limitations, and object adds
Work cost can substantially increase, and lose the market competitiveness.
The content of the invention
Present invention aim at, debug time long defect, there is provided larger for existing AWS/PCS duplexers volume
Kind miniaturization, easy processing, the band logical of low cost add the AWS/PCS duplexers realized with resistance.
The present invention to achieve the above object, is adopted the following technical scheme that：
A kind of band logical adds the AWS/PCS duplexers realized with resistance, including cavity and cover plate, have on the cavity public port,
First port and second port, it is characterised in that：There is bandstop filter and all the way bandpass filter all the way, institute in the cavity
State first port to be connected with the bandstop filter, the second port is connected with the bandpass filter.
It is further characterized by：The bandpass filter is the rectangular cavities for being provided with multiple resonant columns.
The bandstop filter include band resistance main line and it is multiple with described with hindering the resonator that is connected of main line.
Preferably：The band resistance main line is band resistance copper sheet.
Band resistance adjusting screw is provided with each described resonator.
Multiple resonators are disposed in parallel in the band resistance main line side, and the bandpass filter is arranged on the band resistance
Main line opposite side, the first port and second port are disposed in parallel in the same side of the cavity.
By the way of band logical adds band to hinder, highly effective diminution volume only needs two-way to achieve that AWS/PCS to the present invention
Duplexer, realizes duplexer miniaturization.And simple structure of the present invention, it is easy to process and debugs.
Brief description of the drawings
Fig. 1 is existing AWS/PCS duplexers partial structural diagram.
Fig. 2 is the AWS/PCS duplexer cavity schematic diagrames designed using band resistance plus band logical.
Specific embodiment
A kind of band logical as shown in Figure 2 adds the AWS/PCS duplexers realized with resistance, including cavity 1 and cover plate（Do not drawn in figure
Go out）, cavity 1 and cover plate are in mating connection.There is public port 2, first port 3 and second port 4 on the cavity 1, it is described
There is bandstop filter 7 and all the way bandpass filter 9 all the way, the first port 3 and the phase of the bandstop filter 7 in cavity 1
Connection, the second port 4 is connected with the bandpass filter 9.
The bandpass filter 9 is the rectangular cavities for being provided with multiple resonant columns 10.
The bandstop filter 7 include band resistance copper sheet 8 and it is multiple with described with hindering the resonator 5 that is connected of copper sheet 8, each institute
State and band resistance adjusting screw 6 is provided with resonator 5.
Multiple resonators 5 are disposed in parallel in band resistance copper sheet 8 side, and the bandpass filter 9 is arranged on described
The band resistance opposite side of copper sheet 8, the first port 3 and second port 4 are disposed in parallel in the same side of the cavity 1.
The above is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert
Specific implementation of the invention is confined to these explanations.For any people for being familiar with this technology and its field, this hair is not being departed from
On the premise of bright design, various deductions or change may be made, should all belong to protection scope of the present invention.
