Description

Low-loss high stability 4GGSM filter
Technical field
The utility model relates to wave filter technology field, particularly relates 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 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 4GGSM filter.
The utility model is achieved through the following technical solutions:
A kind of low-loss high stability 4GGSM 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, seven TDD-LTE signal resonance frequency control levers and near-end and far-end inhibitory control element intercoupled are installed in the inside of resonant cavity, multiple L-type signal isolation guide plate is provided with in intra resonant cavity, multiple coupling bar is connected with between seven TDD-LTE signal resonance frequency control levers, the periphery plating silver layer of TDD-LTE signal resonance frequency control lever is positioned in the inside of resonant cavity, the TDD-LTE signal resonance frequency control lever being positioned at left side and right side is connected to signal input transmission line and signal output 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.
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 advantage unobstructed, convenient for installation and maintenance of signal, effectively can offset interference.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model covering plate structure schematic diagram.
Embodiment
As Fig. 1, shown in 2, a kind of low-loss high stability 4GGSM filter, include resonant cavity 1, cover plate 2 is fixed with on resonant cavity 1, signal input port N Connector 3 and signal output port N Connector 4 is separately installed with at the left and right sides of resonant cavity 1, seven TDD-LTE signal resonance frequency control levers 5 and near-end and far-end inhibitory control element 6 intercoupled are installed in the inside of resonant cavity 1, multiple L-type signal isolation guide plate 10 is provided with in resonant cavity 1 inside, multiple coupling bar 11 is connected with between seven TDD-LTE signal resonance frequency control levers 5, the periphery plating silver layer 7 of TDD-LTE signal resonance frequency control lever 5 is positioned in the inside of resonant cavity 1, the TDD-LTE signal resonance frequency control lever 5 being positioned at left side and right side is connected to signal input transmission line 8 and signal output transmission line 9, described signal input transmission line 8 exports transmission line 9 with signal and is connected with signal input port N Connector 3 and signal output port N Connector 4 respectively.
