Abstract
The utility model discloses a kind of band logical and added on the AWS/PCS duplexers realized with resistance, including cavity and cover plate, the cavity with 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, the first port is connected with the bandstop filter, and the second port is connected with the bandpass filter in the cavity.The utility model is by the way of band logical adds band to hinder, and highly effective diminution volume only needs two-way to achieve that AWS/PCS duplexers, realizes duplexer miniaturization.And the utility model is simple in construction, it is easy to process and debugs.
Description
Technical field
The utility model belongs to electronic communication technology field, and more particularly to a kind of band logical adds the AWS/PCS realized with resistance
Duplexer.
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 also require that miniaturization to the volume of product.
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 need real with No. three bandpass filters
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
The utility model purpose be for existing AWS/PCS duplexers volume it is larger, the defect of debug time length is carried
A kind of band logical for miniaturization, easy processing, low cost adds the AWS/PCS duplexers realized with resistance.
The utility model to achieve the above object, is adopted the following technical scheme that：
A kind of band logical, which adds on the AWS/PCS duplexers realized with resistance, including cavity and cover plate, the cavity, has common port
Mouth, first port and second port, it is characterised in that：There is bandstop filter and all the way bandpass filtering all the way in the cavity
Device, the first port is connected with the bandstop filter, and 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 is included with resistance main line and multiple resonators being connected with band resistance main line.
It is preferred that：The band resistance main line is band resistance copper sheet.
Band resistance adjusting screw is provided with each 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.
The utility model is by the way of band logical adds band to hinder, and highly effective diminution volume only needs two-way to achieve that
AWS/PCS duplexers, realize duplexer miniaturization.And the utility model is simple in construction, 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 using the AWS/PCS duplexer cavity schematic diagrames with resistance plus band logical design.
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 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 is included with resistance copper sheet 8 and multiple resonators 5, Mei Gesuo being connected with band resistance copper sheet 8
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.
Described above is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For any people for being familiar with this technology and its field, not
On the premise of departing from the utility model design, various deductions or change may be made, should all belong to protection of the present utility model
Scope.
