[embodiment]
Be further described the utility model below in conjunction with accompanying drawing and exemplary embodiment, wherein identical in accompanying drawing label all refers to identical parts.In addition, if the detailed description of known technology is for illustrating that feature of the present utility model is unnecessary, then omitted.
Fig. 2 to Fig. 4 collectively illustrates mixer of the present utility model, for the frequency range of 800-2200MHz, avoids the mutual crosstalk of multiple resonance path.
Coaxial resonant column in diagram individual channel only illustrates one, and do not mean that in mixer of the present utility model, each resonance path is only provided with a coaxial resonant column, why only illustrating one, is the implementation for the ease of understanding signal combiner between public port of the present utility model and four paths.
The cover plate 7 that this mixer 100 comprises cavity 1, cover mutually with cavity 1, be located at outside cavity 1 and with four resonance paths 10, four signal ports (scheme not show, lower with) and a public port 2 one to one.Described four signal port one_to_one corresponding are by the signal of two standard up-downgoings, four frequency ranges, and described public port 2 is for the conjunction road signal by four resonance paths.
Form four resonance paths 10 by some dividing plates 4 in described cavity 1, and form a public resonant cavity 20 be all communicated with four resonance paths 10 in the position near public port 2.Multiple coaxial resonant column 15 is equipped with in each resonance path 10, coupling window (not shown) is provided with between adjacent two coaxial resonant columns 15, wherein, be first coaxial resonant column of this path closest to a coaxial resonant column of public resonant column in each resonance path, a coaxial resonant column closest to signal port is last coaxial resonant column of this path; Public resonant column 25 is provided with, first in each resonance path 10 coaxial resonant column 15 and public resonant column 25 magnetic Field Coupling in described public resonant cavity 20.Be capacitive coupling between described public resonant column 25 and public port 2.
Incorporated by reference to Fig. 4, well-known, the frequency range of each path is determined by the height of coaxial resonant column 15, finely tunes via resonant rod 8.When the signal of public port 2 is coupled in four paths by public resonant column 25, because the coupling amount between public resonant column 25 and each resonance path 10 (being also each path) first coaxial resonant column 15 is different, and then make the bandwidth of every road signal different, thus send via the signal port of correspondence, achieve the shunt of frequency range.When this mixer 100 works in and closes road, the signal of four paths is coupled to public port 2 by public resonant column 25 and outwards transmission, thus achieves the combiner transmission of two standard four road signals.
Owing to not needing to arrange multistage conjunction road to realize the combiner of signal, mixer of the present utility model does not need more public resonant cavity 20, thus decrease the number of public resonant cavity 20 and public resonant column 25, and then reduce the volume of cavity, reduce cost.
