Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1 and Fig. 2.The coupler of the present embodiment comprises cavity 1, chamber lid 2, input port 3, output port 4, first coupling port 5, first load port 6, second coupling port 7, second load port 8, transmission conductor 9, first coupling conductors 10 and the second coupling conductors 11.
Chamber lid 2 is placed on cavity 1 and forms accommodation space with cavity 1, and transmission conductor 9, first coupling conductors 10 and the second coupling conductors 11 are arranged in accommodation space.Input port 3 and output port 4 are arranged at the opposite end of cavity 1 respectively, and the two ends of transmission conductor 9 are connected with input port 3, output port 4 respectively, first coupling port 5, first load port 6, second coupling port 7, second load port 8 is arranged at the side of cavity 1, and the two ends of the first coupling conductors 10 are connected with the first coupling port 5 and the first load port 6 respectively, the two ends of the second coupling conductors 11 are connected with the second coupling port 7 and the second load port 8 respectively.Transmission conductor 9 comprises integrated first transmission body 91 and the second transmission body 92, the width of the first transmission body 91 is greater than the width of the second transmission body 92, it is parallel that first coupling conductors 10 and first transmits body 91, it is parallel that second coupling conductors 11 and second transmits body 92, and the first coupling conductors 10 and the first gap of transmitting between body 91 are greater than the second coupling conductors 11 and second transmits gap between body 92.
In the present embodiment, the width of the first coupling conductors 10 equals the width of the first transmission body 91, and the width of the second coupling conductors 11 equals the width of the second transmission body 92.
Operationally, the first coupling conductors 10 near input port 3 realizes the coupling of input signal power to the coupler of the embodiment of the present invention, and the first coupling port 5 exports coupled signal, and the first load port 6 connects load; The second coupling conductors 11 near output port 4 realizes the coupling of reflection signal power, and the second coupling port 7 exports coupled signal, and the second load port 8 connects load.
Wherein, width due to the first transmission body 91 is greater than the width of the second transmission body 92, and the first coupling conductors 10 and the first gap of transmitting between body 91 are greater than the second coupling conductors 11 and second transmits gap between body 92, the operating frequency range of coupler thus can be increased on the basis not increasing impedance line joint number.And because the first load port 6 and the second load port 8 can external loads, the operating frequency range of coupler therefore can be regulated by connecting different loads.
When powerful signal forward is by coupler, namely signal inputs from input port 3, exports from output port 4, and the ratio of the signal magnitude that the first coupling port 5 exports and high-power signal size is input power overlapping index; When powerful signals reverse is by coupler, namely signal inputs from output port 4, exports from input port 3, the ratio of the signal magnitude that the second coupling port 7 exports and high-power signal size is reflection power overlapping index, two kinds of degree of coupling curve co-insides can be found out from the input power degree of coupling and reflection power degree of coupling emulated data curve, and rise greatly with the change of frequency.
By the way, the coupler of the embodiment of the present invention by arranging two sections of coupling conductors, thus can realize bidirectional coupled, can increase the operating frequency range of cavity coupler.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
