Abstract
The utility model discloses a kind of low-loss high stability 4GDCS filter, signal input port N Connector and signal output port N Connector is separately installed with at the left and right sides of resonant cavity, in intra resonant cavity, nine TDD-LTE signal resonance frequency control levers and near-end and far-end inhibitory control element intercoupled are installed, wherein eight TDD-LTE signal resonance frequency control levers divide two row four to arrange arrangement, be positioned at two TDD-LTE signal resonance frequency control levers of same row not on same vertical curve, another one TDD-LTE signal resonance frequency control lever is positioned at the centre position, left side of two row TDD-LTE signal resonance frequency control levers, the periphery plating silver layer of nine TDD-LTE signal resonance frequency control levers is positioned in the inner side of resonant cavity.The utility model has that loss is little, overall dimensions are little, is designed beautifully, the plurality of advantages such as convenient for installation and maintenance, effectively can offset interference.
Description
Technical field
The utility model relates to wave filter technology field, particularly relates to a kind of low-loss high stability 4GDCS filter.
Background technology
Existing all kinds of antenna and transceiver input port be not low-loss, selective filter all or adopt irradiation structure and the multi-cavity resonance structure of solid type, bulky, complex structure, processing difficulties, become the major obstacle of wireless communications products microminiaturization: its main cause to be the radiation transformed space of its institute's foundation and frequency resonance space be electrolyte constant close to 1, the free air that loss is minimum.Opening up the solution electric constant of various different size and controlled, and separating the lower new material replacement free air of matter loss, is realize antenna and filter complanation, microminiaturization and intelligentized Major Technology.
Utility model content
The utility model object is exactly the defect in order to make up prior art, provides a kind of low-loss high stability 4GDCS filter.
The utility model is achieved through the following technical solutions:
A kind of low-loss high stability 4GDCS filter, include resonant cavity, cover plate is fixed with on resonant cavity, signal input port N Connector and signal output port N Connector is separately installed with at the left and right sides of resonant cavity, in intra resonant cavity, nine TDD-LTE signal resonance frequency control levers and near-end and far-end inhibitory control element intercoupled are installed, wherein eight TDD-LTE signal resonance frequency control levers divide two row four to arrange arrangement, be positioned at two TDD-LTE signal resonance frequency control levers of same row not on same vertical curve, another one TDD-LTE signal resonance frequency control lever is positioned at the centre position, left side of two row TDD-LTE signal resonance frequency control levers, the periphery plating silver layer of nine TDD-LTE signal resonance frequency control levers is positioned in the inner side of resonant cavity, the TDD-LTE signal resonance frequency control lever being positioned at the leftmost side is connected with signal input transmission line, the TDD-LTE signal resonance frequency control lever being positioned at the rightmost side is connected with signal and exports transmission line, described signal input transmission line exports transmission line with signal and is connected with signal input port N Connector and signal output port N Connector respectively.
When intra resonant cavity plus signal by time, a kind of electromagnetic energy can be produced between two resonance frequencys, be undertaken mutually transmitting by electromagnetic field couples mode and connect.
Be connected by producing magnetic field during signal when near-end powers up with TDD-LTE signal resonance frequency control lever with far-end inhibitory control element.
The utility model has the advantages that: the utility model has that loss is little, overall dimensions are little, is designed beautifully, the special defeated plurality of advantages such as unobstructed, convenient for installation and maintenance of signal, effectively can offset interference, system is worked under the condition of full code channel, therefore, spectrum efficiency is high, can meet following expansion demand.
