Abstract
The invention discloses a low-loss high-stability 4GGSM filter. The filter comprises a resonant cavity, wherein a cover plate is fixed on the resonant cavity, a signal input port N-shaped connector and a signal output port N-shaped connector are installed on left and right sides of the resonant cavity respectively, seven TDD-LTE signal resonant frequency joysticks which are coupled with one another as well as a near end and far end suppression control element are installed in the resonant cavity, a silver layer is electroplated in positions, which are located on peripheries of the TDD-LTE signal resonant frequency joysticks, inside the resonant cavity, and a signal input transmission line and a signal output transmission line are connected onto the TDD-LTE signal resonant frequency joysticks located on left and right sides respectively. The filter has the advantages of low loss, small external dimension, attractive design, smoothness in signal transmission and convenience in installation and maintenance and can offset interference effectively.
Description
Technical field
The present invention relates to wave filter technology field, relate in particular to a kind of low-loss high stability 4GGSM 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 be the radiation transformed space of its institute's foundation and frequency resonance space be electrolyte constant close to 1, the free air of loss minimum.Opening up the solution electric constant of various different sizes and controlled, and separating the lower new material replacement free air of matter loss, is to realize antenna and filter complanation, microminiaturization and intelligentized Major Technology.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, and a kind of low-loss high stability 4GGSM filter is provided.
The present invention is achieved by the following technical solutions:
A kind of low-loss high stability 4GGSM filter, include resonant cavity, on resonant cavity, be fixed with cover plate, be separately installed with signal input port N Connector and signal output port N Connector at the left and right sides of resonant cavity, seven TDD-LTE signal resonance frequency control levers that intercouple and near-end and far-end inhibitory control element are installed in the inside of resonant cavity, be provided with multiple L-type signal isolation guide plates in intra resonant cavity, between seven TDD-LTE signal resonance frequency control levers, be connected with multiple coupling bars, silver layer is electroplated in the periphery that is positioned at TDD-LTE signal resonance frequency control lever in the inside of resonant cavity, on the TDD-LTE signal resonance frequency control lever that is positioned at left side and right side, be connected with respectively signal input transmission line and signal output transmission line, described signal input transmission line is connected with signal input port N Connector and signal output port N Connector respectively with signal output transmission line.
Advantage of the present invention is: the present invention has advantages of that loss is little, overall dimensions are little, is designed beautifully, signal is specially defeated unobstructed, convenient for installation and maintenance, can effectively offset interference.
