Abstract
The utility model discloses a novel electric cross coupling structure which comprises a housing (1), a cavity (2) surrounded by the housing (1), as well as a resonance rod A (3), a resonance rod B (4) and a resonance rob C (5) which are arranged in the cavity (2) in a linear structure; and a metallic conductor band (7) is arranged on an electric coupling panel (6) which is also arranged in the cavity (2). The electric cross coupling structure has the benefits of simple structure and easiness in realization; the electric cross coupling of non-adjacent resonance rods in a filter where the resonance rods are arranged in a linear manner is realized; as a transmission zero is introduced in the filter response, better out-band rejection of the filter is realized, and the selectivity is improved.
Description
Technical field
The utility model relates to the microwave communication field, particularly a kind of novel electric cross coupling structure.
Background technology
Filter is one of indispensable device of wireless communication system, and wireless communication system frequency resource in short supply further is also increasingly high to the requirement of the performance index of filter.Because the interval between the frequency spectrum is more and more littler, thereby interference each other will be more and more obvious, for avoiding this interference, then needs the filter of high selectivity, promptly have the filter of higher band outside inhibitory ability.In order to realize higher inhibition degree index, then need adopt generalized Chebyshev filter, i.e. the cross-couplings filter.The cross-couplings filter need utilize the cross-couplings between the non-adjacent resonators in filter response, to introduce transmission zero, thereby the stopband of filter response curve is more precipitous, suppresses Du Genggao.
It is structural folding that traditional coaxial cavity filter realizes that cross-couplings generally needs; Be being staggered of resonant cavity; But some path must be that linear pattern is arranged in the multipath mixer, thereby staggered cavity body filter obviously here is inapplicable.
The utility model content
The purpose of the utility model is to overcome the shortcoming of prior art, and a kind of novel electric cross-linked structure of realization in the linear pattern filter is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of novel electric cross coupling structure; It comprises interior resonant rod A, the resonant rod B resonant bar C that arranges with linear structure of cavity, cavity that housing, housing surround; Also be provided with the electric coupling plate in the cavity; The inwall of described housing is provided with cylindrical boss, and on cylindrical boss, described electric coupling plate is provided with the metallic conductor band to the electric coupling plate by screw.
The utlity model has following advantage:
1, the utility model simple in structure, be easy to realize; Can in the resonant rod filter that linearly type is arranged, realize electric cross-couplings very easily; Thereby when having avoided, need structural folding, be applicable to microwave pectination cavity body filter as cavity body filter realization cross-couplings.
2, in the linear pattern filter, realized the electric cross-couplings between the non-adjacent resonant rod through the electric coupling plate, in filter response, introduced transmission zero, thereby realized that filter suppresses outside being with preferably, has improved selectivity.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The structural representation of the electric coupling plate of Fig. 2 the utility model.
Among the figure, 1-housing, 2-cavity, 3-resonant rod A, 4-resonant rod B, 5-resonant rod C, 6-electric coupling plate, 7-metallic conductor band, 8-cylindrical boss.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description:
As shown in Figure 1; A kind of novel electric cross coupling structure; It comprises resonant rod A3, the resonant rod B4 resonant bar C5 that arrange with linear structure in cavity 2 that housing 1, housing 1 surround, the cavity 2, on the inwall of housing 1 sidewall parallel with three resonant rod orientations, is provided with cylindrical boss 8, is fixed with electric coupling plate 6 on the cylindrical boss 8; As shown in Figure 2, described electric coupling plate 6 is provided with metallic conductor band 7.
The cross-couplings that electric coupling plate 6 is realized between resonant rod A3 and the resonant rod C5 through the metallic conductor band 7 that applies in the above; Through changing the height of electric coupling plate 6; Can change the size of electric cross-couplings amount; Electric coupling plate 6 is high more from the height of cavity 2 short-circuit ends, and the distance of promptly leaving cavity 2 open ends is near more, and then electric cross-couplings amount is big more.
