Abstract
The present invention relates to a kind of adjustable input coupling structures in filter product, including outer conductor, and inner wire is equipped in outer conductor, it is characterised in that：One end housing of inner wire is useful for the axle sleeve that outer conductor is isolated with inner wire, another end of inner wire is interior with set on outer conductor and the adjusting bolt made of nonmetallic materials is fixedly connected.It is an advantage of the invention that：Ensure to be adjusted under function originally, realize do not generate intermodulation characteristic is easy to process simultaneously, installation, dismounting are simple.
Description
Technical field
The present invention relates to a kind of adjustable input coupling structures in filter product, belong to indoor mobile communication system
System technical field.
Background technology
Communication coaxial filter product, such as duplexer, triplexer, multiplexer etc., usually using perception (contact)
Or capacitive (contactless) input coupling structure.And coaxial filter product all-pass band it is adjustable be product serial it is unitized and at
The important measures of this control, and change the important support of frequency and upgrading to product and communication system future.Pass through adjustable input
The variable advantage of coupling length is more easy to design covering all-pass band, the multiplexer product haveing excellent performance, and capacitively coupled knot
Structure is easiest to realize tuning into the melt for filter product.But input coupling tunes into the melt the intermodulation for bringing filter product and standing wave
The problem of stability.
The existing adjustable input coupling structure in filter product as shown in Figure 1, including inner wire 1, lead outside
Body 2, shrapnel contact point 3, adjusting bolt contact point 4.The shortcomings that above structure, is：It needs to be realized with contact resilient component,
Processing technology is relative complex, and material selection is stringent；The axial movement in outer conductor 2 of inner wire 1, it is desirable that all needed in any position
The good contact for keeping inner and outer conductor will appear in temperature change, and repeatedly after debugging and contact unstable situation；Often
It is secondary debugged after need additional fixing piece, so that thread contact is stablized.
Invention content
The purpose of the present invention is：Ensure to be adjusted under function originally, does not generate intermodulation.
In order to achieve the above object, the technical solution of the present invention is to provide a kind of for adjustable in filter product
Input coupling structure, including outer conductor are equipped with inner wire in outer conductor, it is characterised in that：One end housing of inner wire
Be useful for the axle sleeve that outer conductor is isolated with inner wire, another end of inner wire in outer conductor and by non-metallic material
Adjusting bolt is fixedly connected made of material.
Preferably, between another end and the adjusting bolt of the inner wire one is fastened on by stick
It rises.
It is an advantage of the invention that：Ensure to be adjusted under function originally, realizes the characteristic for not generating intermodulation while the side of processing
Just it, installs, dismantle simply.
Description of the drawings
Fig. 1 is the existing schematic diagram for the adjustable input coupling structure in filter product；
Fig. 2 is the structural schematic diagram of the present invention.
Specific implementation mode
In order to make the present invention more obvious and understandable, hereby with preferred embodiment, and attached drawing is coordinated to be described in detail below.
As shown in Fig. 2, a kind of adjustable input coupling structure in filter product provided by the invention includes interior
Conductor 1, outer conductor 2, PTFE- axle sleeves 5 and Ultem- adjusting bolts 6.The inner wire of metal material and nonmetallic materials
Ultem- adjusting bolts 6 are fixed together using happy safe glue 401 with 770 sticks.PTFE- axle sleeves 5 are for stablizing isolation inner wire 1
With outer conductor 2, the capacitive coupling between contactless metal and metal is formed.Ultem- adjusting bolts 6 are by dielectric material
It is manufactured, realize that adjustable input coupling does not generate intermodulation issues.
The present invention removes original elastic part, reduces process and assemble difficulty.Meanwhile for the difference of filter product
Frequency requirement, the diameter of inner conductors, half bush wall thickness, length carry out corresponding simulation calculation and optimization, make its frequency domain standing wave
It can be best.
