Abstract
The utility model, which relates to the communication equipment field, discloses a high-frequency directional coupler. The coupler has a cavity structure in an X shape; and the length of the formed coupled window is 6.55mm and the width thereof is 2.84mm. According to the utility model, when signals are inputted at an input terminal, a portion of signals are outputted from an output terminal straightly and another portion of signals are coupled from a coupled terminal, so that the directional coupling energy with the coupling degree of 3db can be outputted from the coupled terminal at the high working frequency of 42G. The high-frequency directional coupler has advantages of simple structure and economic performance.
Description
Technical field
The utility model relates to communication equipment field, particularly relates to a kind of high frequency directional coupler.
Background technology
Directional coupler is a kind of four port networks, is passive and reciprocal networks.In theory, directional coupler is zeroloss circuit, and its each port all should mate.Fig. 1 shows the structural representation of a kind of directional coupler in the prior art, with reference to diagram, when signal was inputted from input 1, most of signal was from output 2 straight-through outputs, wherein the sub-fraction signal is coupled out from coupled end 3, and isolation end 4 connects a matched load usually.Under the 42G high operate frequency, be difficult to realize the directional couple of degree of coupling 3db with the prior art device.
The utility model content
The technical problem that (one) will solve
The technical problems to be solved in the utility model is to overcome defective of the prior art, and a kind of high frequency directional coupler is provided, and is implemented under the 42G high operate frequency directional couple of degree of coupling 3db.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of high frequency directional coupler, and described coupler is cavity body structure, and is set to the X-type structure, and the coupling window of its formation is of a size of the wide 2.84mm of long 6.55mm*.
Wherein, described coupler comprises four ports, is respectively input, output, coupled end and isolation end.
Wherein, the size of described four ports is the wide 2.84mm of long 4.37mm*.
(3) beneficial effect
The high frequency directional coupler that technique scheme provides, when signal is inputted from input, part signal is from the straight-through output of output, another part signal is coupled out from coupled end, realized under the 42G high operate frequency, the directional couple energy of coupled end output degree of coupling 3db, structure is simpler, and is more economical.
Description of drawings
Fig. 1 is the structural representation of directional coupler in the prior art;
Fig. 2 is the structural representation of the utility model embodiment directional coupler;
Fig. 3 is that A-A among Fig. 2 is to view.
Wherein, 1: input; 2: output; 3: coupled end; 4: isolation end.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Fig. 2 shows the structural representation of present embodiment high frequency directional coupler, and Fig. 3 is that A-A among Fig. 2 is to view.See figures.1.and.2, this high frequency directional coupler is cavity body structure, and is set to the X-type structure, and the coupling window of its formation is of a size of the wide 2.84mm of long 6.55mm*.
Particularly, described coupler comprises four ports, is respectively input 1, output 2, coupled end 3 and isolation end 4; The size of described four ports is the wide 2.84mm of long 4.37mm*.What coupled end 3 was exported is the directional couple energy of degree of coupling 3db.Thus, by the cavity design of present embodiment coupler, and the coupling window size is set to the wide 2.84mm of long 6.55mm*, can realize device under the 42G high operate frequency, the directional couple of degree of coupling 3db satisfies the coupling needs, and simple in structure, realize that easily cost is low.
As can be seen from the above embodiments, when the utility model is inputted from input when signal, part signal is from the straight-through output of output, another part signal is coupled out from coupled end, realized under the 42G high operate frequency, the directional couple energy of coupled end output degree of coupling 3db, structure is simpler, and is more economical.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection range of the present utility model.
