Abstract
The utility model discloses a cavity two-way power divider, which comprises a cavity and an inner conductor, wherein two ends of the cavity serve as an input end and an output end respectively, the inner conductor is mounted inside the cavity, the inner conductor is a reducing metal bar comprising two steps, and the diameter of each section of the reducing metal bar increases gradually from the input end to the output end. The embodiment of the utility model has the advantages that the structure is simple, the work is reliable, and the working frequency ranges from 350 MHZ to 850 MHZ.
Description
[technical field]
The utility model relates to power splitter, relates in particular to a kind of cavity two power splitters.
[background technology]
The cavity power splitter is the requisite passive device in the communication link, and the inner wire of common cavity two power splitters mostly is the stepped cylinder of 4-5 level and forms.Though its frequency coverage is bigger, structure is complicated, not too is suitable for the little use occasion of operating frequency coverage requirement.
[summary of the invention]
The technical problems to be solved in the utility model provides cavity two power splitters of a kind of operating frequency range from 350MHz to 850MHz.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of cavity two power splitters, comprise cavity and inner wire, the cavity two ends are respectively input and output, inner wire is installed in the cavity, and inner wire is the diameter metal rod that is made of 2 joint ladders, and the diameter of stepped each section of diameter metal rod increases from the input to the output gradually.
The beneficial effects of the utility model are that simple in structure, operating frequency range is from 30MHz to 850MHz.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model example structure figure.
Fig. 2 is a diameter metal bar structure schematic diagram.
Among Fig. 1,1-cavity, 2-metal bar.
[embodiment]
Be a kind of cavity two power splitters as shown in Figure 1, comprise cavity 1 and as the stepped diameter metal rod 2 of inner wire, cavity one end is respectively input, the other end is an output, and stepped diameter metal rod 2 is installed in the cavity, and an end of stepped diameter metal rod 2 is connected with input, the other end is connected with output, diameter metal rod 2 is made of 2 joint ladders, and from the input to the output, the diameter of its each section increases gradually.Because it is operated in the low side frequency range, its actual volume ratio is bigger, and particularly Zheng Ti length is longer.
The operating frequency range of present embodiment is from 350MHz to 850MHz.
Claims (1)
