Abstract
A kind of high power cavity body filter, including shell, capacitive metallic object, metallic object, adjusting screw, adjusting screw and biography turn line interface, separating in the shell has multiple resonant cavities, it is equipped with capacitive metallic object and metallic object in each resonant cavity, capacitive metallic object and metallic object are in open column shape body, capacitive metallic object is fixed on shell, metallic object is sleeved in the cavity of capacitive metallic object, metallic object side is equipped with adjusting screw, shell between adjacent resonators is equipped with adjusting screw, it is connected by coupling bar between two resonant cavities of housing central section, shell both sides, which are equipped with to pass, turns line interface, biography turns line interface and is connect with capacitive metallic object across shell.The utility model separates multiple resonant cavities in shell, reduces the volume of filter；In the adjusting screw of metallic object side installation, the power of filter is adjusted by adjusting screw, filter can be improved bears power；The installation and adjustment screw between resonant cavity, the bandwidth of tunable filter.
Description
Technical field
The utility model is related to filter fields, more particularly to a kind of high power cavity body filter.
Background technology
Filter is widely used in the communications field, especially field of radio frequency communication as a kind of frequency selection device.
In the base station of communication system, filter be used to select signal of communication, filter out the clutter or interference signal outside communication signal frequency.
Existing cavity body filter power is low, volume is big, causes frequency degree of suppression poor, and prodigious difficulty is caused to realizing and using.
Invention content
The high power cavity body filter higher and small the purpose of this utility model is to provide a kind of power.
The purpose of this utility model is achieved through the following technical solutions：
A kind of high power cavity body filter, including shell, capacitive metallic object, metallic object, adjusting screw, adjusting screw and biography
Turn line interface, separating in the shell there are multiple resonant cavities, and capacitive metallic object and metallic object, capacitive are equipped in each resonant cavity
Metallic object and metallic object are in open column shape body, and capacitive metallic object is fixed on shell, and metallic object is sleeved on capacitive metallic object
In cavity, it is machined with through-hole on the shell of metallic object side, the adjusting screw for adjusting filter power is installed in through-hole,
Shell between adjacent resonators is equipped with the adjusting screw for adjusting filter bandwidht, two resonant cavities of housing central section it
Between connected by coupling bar, shell both sides, which are equipped with to pass, turns line interface, and biography turns line interface and connect with capacitive metallic object across shell.
The biography turns to be provided with capacitive character metallic object on line interface.
The utility model separates multiple resonant cavities in shell, reduces the volume of filter；It is installed in metallic object side
Adjusting screw, by adjusting screw adjust filter power, filter can be improved bears power；Pacify between resonant cavity
Fill adjusting screw, the bandwidth of tunable filter.The utility model is simple in structure, processing cost is low, convenient for debugging, can be widely
Applied to each field.
