The utility model content
The purpose of this utility model is to overcome above-described shortcoming, provides the coupling of a kind of signal output part and filtering chamber to need not solder joint welding, stable high tap integral type mixer.
For achieving the above object, concrete scheme of the present utility model is as follows: a kind of tap integral type mixer, include housing, the inner chamber of described housing is divided into several filtering chambeies by isolation bar, be provided with a plurality of resonance posts in each filtering chamber, be provided with coupling window between the adjacent two resonance posts in the same filtering chamber, the rear end in each filtering chamber is equipped with signal input part, middle filtering chamber front end in described several filtering chambeies is provided with signal output part, other filtering chambeies except that middle filtering chamber communicate and form a common cavity in signal output part one side, described common cavity is provided with some public resonance posts, the tap of described signal output part is coupled in public resonance post, the signal coupling is carried out by the tap of public resonance post and signal output part in other filtering chambeies except that middle filtering chamber, filtering chamber in the middle of the tap of described signal output part is coupled directly to.
Wherein, the coupled modes of the public resonance post of the tap of described signal output part and described common cavity are the direct feed coupling.
Wherein, the public resonance post of the tap of described signal output part and common cavity is formed in one.
Wherein, the coupled modes between the described public resonance post are the direct feed coupling.
Wherein, the upper end around described isolation bar upper end and the shell is provided with the shielding groove.
