Equal, or the distance between described first coupling disc 400 and upper public resonant column 301 more than described first coupling disc 400 with
Under distance between public resonant column 303, or the distance between described first coupling disc 400 and upper public resonant column 301 is little
In described first coupling disc 400 and under distance between public resonant column 303.
Further, when the first coupling disc 400, closer to upper public resonant column 301, (the such as first coupling disc is positioned at first
Above coupling aperture) when, the public port bandwidth that can be regulated lower floor's path by expanding or shrinking the first coupling aperture 500 is divided
Join.Otherwise, when the first coupling disc 400 closer under public resonant column 303 when, then can be by expanding or shrinking the first coupling aperture
The 500 public port bandwidth distribution regulating upper strata path.
In other embodiments, when upper resonant column is the 301st, the 302nd, 305 the 303rd, the 304th, 306 right up and down two-by-two with lower resonant column
Qi Shi, it is also possible to by expanding or shrinking coupling aperture or moving up and down coupling disc and realize that the bandwidth of upper and lower two-layer path is divided
Join.
In summary, in combiner of the present utility model, can by arrange the first coupling disc and public port joint with
Position (namely the distance between the first coupling disc and upper and lower public resonant column) between first coupling aperture, the size of coupling aperture
And the distance that staggers of upper and lower public resonant column, realize the bandwidth distribution of upper and lower filtering path.
Seeing Fig. 6, Fig. 6 is the measured drawing of the S parameter of combiner of the present utility model.S parameter curve demonstrates, common port
Two paths of Dual-layer at mouth joint 200 are respectively assigned with nearly 250MHz port bandwidth, and the return loss in S curve is equal
At below-20dB, the isolation of each frequency range also at below 30dB, meet Modern Mobile Communications Systems to wave filter miniaturization, low
Insertion Loss, the demand of high suppression.
Combiner of the present utility model can be widely applied in Modern Mobile Communications Systems, and wherein, upper strata cavity three leads to
The frequency range of band is 1699MHz-1912MHz, and the frequency range of three passbands of lower floor is 1928MHz-2174MHz.
The above is only some embodiments of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from the utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
