The beneficial effects of the utility model are that: can make coupling coefficient big, realize the coupling of broad passband port easily, the coupling coefficient uniformity is high, can can effectively increase interval between resonance plate and the upper cover plate than on the low side under the normal condition at resonant frequency, it is big to improving the help of 3 jie's intermodulations, exempt from the welding, improve the intermodulation percent of pass, the assembly is simple, improves work efficiency, practices thrift the cost.
Description
Technical field
The utility model relates to communication technical field, particularly a kind of low frequency tep reel resonant column port.
Background technology
Wideband wireless mobile communication has become global communications industry and has developed one of industrial field of greatest concern, in the past few decades, along with the develop rapidly of modern wireless telecommunications, communication relevant industries, radio-frequency module has irreplaceable position in wireless communication technology, has a wide range of applications.
But low frequency tep reel resonant column port capacitive coupling mode existing defects at present, existing processing disadvantages has: consistency is poor, and batch production fraction defective is high; Pad is uncontrollable, easily causes intermodulation bad, has a strong impact on 3 Jie's intermodulations; Have a strong impact on resonance frequency, resonance frequency can be made higher, thus resonance plate and cover plate spacing are reduced, safe distance herein often can be made not enough.Along with more and more higher bandwidth demand, the requirement of device fabrication to the technique that low frequency tep reel resonant column port is coupled is also more and more higher, can provide comparatively high coupling coefficient, easily realize comparatively broad passband port coupling, keep coupling coefficient consistency simultaneously, and effectively can increase resonance plate and upper cover plate spacing when resonance frequency is lower than normal condition, improve 3 Jie's intermodulations, the technical solution exempting to weld is needed badly most.Meanwhile, equipment assembling process also demand fulfillment simply assemble, increase work efficiency, can be cost-saving.
Utility model content
The purpose of this utility model is a kind of low frequency tep reel resonant column port provided to solve above-mentioned the deficiencies in the prior art.These coupled modes can make coupling coefficient large, easily realize comparatively broad passband port coupling; Coupling coefficient consistency is high; Than on the low side under normal circumstances, spacing between resonance plate and upper cover plate can be effectively increased in resonance frequency; Intermodulation help is situated between greatly to raising 3, exempts from welding, improve intermodulation percent of pass; Assembling is simple, increases work efficiency, cost-saving.
To achieve these goals, a kind of low frequency tep reel resonant column port designed by the utility model, comprise tuning screw, resonant column, dielectric, tap line and resonant column installation step, described resonant column is arranged on described resonant column installation step, the upper end of described resonant column is connected with described tuning screw, it is inner that described dielectric is embedded in described resonant column, and described tap line is connected with described resonant column by described dielectric.
Further, a kind of low frequency tep reel resonant column port, described resonant column is provided with dielectric installing hole.
Further, a kind of low frequency tep reel resonant column port, the material of described dielectric is the insulating material that any dielectric constant is greater than 1.
Further, a kind of low frequency tep reel resonant column port, described tap line connects any type of radio frequency, microwave cable or joint.
A kind of low frequency tep reel resonant column port that the utility model obtains, consistency is higher, and batch production yields is high; Solderless contact, can not have a strong impact on 3 Jie's intermodulations; Do not affect resonance frequency, resonance frequency can be made lower than normal condition, thus resonance plate and cover plate spacing are increased, keep enough safe distances.
The utility model has the advantage of: (1) these coupled modes can make coupling coefficient large, easily realize comparatively broad passband port coupling; (2) coupling coefficient consistency is high; (3) than on the low side under normal circumstances, spacing between resonance plate and upper cover plate can effectively be increased in resonance frequency; (4) intermodulation help is situated between greatly to raising 3, exempts from welding, improve intermodulation percent of pass; (5) assembling is simple, increases work efficiency, cost-saving.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment.
In figure: 1 be tuning screw, 2 are resonant columns, 3 are dielectrics, 4 are tap lines, 5 are resonant column installation steps, 6 is dielectric installing holes.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
