Abstract
The utility model discloses a kind of perceptual cross coupling structures, including resonant rod, the resonant rod includes being located in the middle the second resonant rod and the first resonant rod and third resonant rod positioned at the second resonant rod two sides, simultaneously, it further include flying bar, respectively there is a circular hole at the both ends of the winged bar, while offering threaded hole on the first resonant rod and third resonant rod.The coupled structure flexibility is high, can satisfy the perceptual cross-coupling that product cannot achieve by dimensional problem.
Description
Technical field
The utility model relates to communication equipment fields, and in particular to a kind of perception cross coupling structure.
Background technique
Generally there are Out-of-band rejection or port isolation requirement in the design of the passive radio frequency devices such as filter, combiner,
Especially duplexer requires Out-of-band rejection very high, to meet these requirements usually requires that cross-coupling is added to realize.
Cross-coupling can be divided into capacitive cross coupling and perceptual two kinds of cross-coupling.Capacitive cross coupling is used to inhibit the left side
Passband, perception it is cross-linked be used to inhibit the right passband.Heritage sex-intergrade coupling be two resonant cavities and between open
Window realizes, radiofrequency signal from the first resonant rod to the second resonant rod to third resonant rod, it is just necessary if you need to increase zero point
There is a coupled signal from the first resonant rod to third resonant rod, the effect of window is exactly coupling of first resonant rod to third resonant rod
Close signal.This perception cross-coupling form is suitable in most cases, but there are certain requirements to inside cavity structure, resonance
Chamber must be arranged with similar triangle row shape.
And heritage sex-intergrade coupling there are certain requirements cavity row's cavity configuration.Because size limits in actual product design
Problem can not often be arranged into cavity triangle row shape.It, just can not be in this way if cavity resonant chamber dressing line is arranged
Realize perceptual cross-coupling.
Summary of the invention
The utility model has invented a kind of perceptual cross coupling structure, the coupling aiming at the problem that background technique is proposed
Configuration flexibility is high, can satisfy the perceptual cross-coupling that product cannot achieve by dimensional problem.
The technical scheme is that a kind of perception cross coupling structure, including resonant rod, the resonant rod include being located at
The second intermediate resonant rod and the first resonant rod and third resonant rod positioned at the second resonant rod two sides, meanwhile, it further include solid
Winged bar on first resonant rod and third resonant rod, also, the winged bar is not contacted with affiliated second resonant rod.
Further, respectively there is a circular hole at the both ends of the winged bar, while opening up on the first resonant rod and third resonant rod
There is threaded hole, the winged bar is fixed on the first resonant rod and third resonant rod in such a way that screw is fixed.
Further, the resonant rod is arranged in the way of dressing line.
Further, there is 90 ° of dog-ear at the winged bar both ends.
Further, the winged bar is made of copper material.
Further, the diameter of the circular hole is 3.2cm.
When specific installation, the winged bar is fixed on the resonant rod by M3 screw.
Utility model has the advantages that
1, flexibility is high, can satisfy the perceptual cross-coupling that product cannot achieve by dimensional problem；
2, installation is simple, and stability is high, beats threaded hole on resonant rod, does not have any difficulty when being installed with screw, gold
Belong to screw and the stability that can guarantee product is installed；
3, it can be improved the mutual tone pitch of product, there is no solder joint that can effectively promote intermodulation with silver-plated screw when installation.
4, consistency is high, and resonant rod threaded hole height Cutter Body Processing with Machining Center, precision is easy to guarantee at positive and negative 5
In error, without in addition adjusting cross-linked power.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and embodiments:
Fig. 1 is the structural schematic diagram of the coupled structure；
Wherein: 1, the first resonant rod, the 2, second resonant rod, 3, third resonant rod, 4, winged bar.
Specific embodiment
Embodiment: as shown in connection with fig. 1, described for a kind of perceptual cross coupling structure provided by the invention, including resonant rod
Resonant rod includes being located in the middle the second resonant rod 2 and the first resonant rod 1 and third resonance positioned at 2 two sides of the second resonant rod
Bar 1, meanwhile, it further include flying bar 4, respectively there is a circular hole at the both ends of the winged bar, while on the first resonant rod and third resonant rod
Offer threaded hole.
Certainly the above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow be familiar with technique
People can understand the content of the present invention and implement it accordingly, it is not intended to limit the scope of the present invention.It is all according to this hair
The modification that the Spirit Essence of bright main technical schemes is done, should be covered by the protection scope of the present invention.
