Abstract

The invention relates to a power divider, belonging to the technical field of power dividers. The power divider comprises a shell, a powder dividing bar and a coupler, wherein the shell is internally provided with the powder dividing bar; two ends of the powder dividing bar are respectively connected with a contact pin of the coupler; the shell is connected with a shell of the coupler; the powder dividing bar is divided into two sections; and the two sections are connected with each other by a stud screw thread. By adopting a form of combining an air cavity and an internal conductor, the power divider not only meets the requirements for the coverage bandwidth and the power, but also guarantees the internal conductor not to be easily deformed and to have high fidelity and reduces the requirement on the processing accuracy in the production process, thus improving the production efficiency.

Description

Power splitter

Technical field

The present invention relates to power splitter technical field.

Background technology

The frequency of now widely used chamber power divider is between 800-2500MHz, this frequency covers the main frequency of mobile communication, also contemplated the universal frequency of 3G simultaneously, due to popularizing of Digital Television, the frequency that original analog signal cancels 700MHz gradually is probably used on the product of 3G, if want entirely to be with covering, just need the electric bridge that bandwidth is wider, power splitter, more frequency range can be covered like this, existing power splitter generally adopts microstrip design, its limited bandwidth, power is also very limited, also there is now the design of some chamber power dividers, but face bandwidth restriction too, be difficult to the frequency more than 700-2700MHz, because once bandwidth is widened, inner wire will lengthen, the rigidity of inner wire is just difficult to ensure, very easily be out of shape, the difference of the product that reality is manufactured experimently and emulation is huge, be difficult to practicality at all, and requirement on machining accuracy is high, have impact on production efficiency greatly.

Summary of the invention

The object of this invention is to provide power splitter, the form that it adopts air cavity to be combined with inner wire, not only can meeting the requirement for covering bandwidth, power, and inner wire is not yielding, fidelity is high, reduces the processing request precision in production process simultaneously, thus improves production efficiency.

In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it comprises shell, merit divides rod, hookup, meritorious point of rod is set in described shell, merit divides excellent two ends to be connected with hookup contact pin, shell is connected with hookup shell, described merit divides rod to be divided into two sections, is threaded between two sections by stud.

Described merit is divided rod can arrange 3-5 interface and is connected with hookup contact pin respectively.

The present invention arranges merit to divide rod in the enclosure, and merit divides rod to be divided into two sections, and one section is 1,2,3 grade, thinner, another section is 4,5,6,7 grades, more slightly, connects into a whole merit divide rod between two sections by screwed tight, due to the contraction in length of every section, machining deformation is very little, thus ensure that machining accuracy, and then whole merit divides excellent two ends to be connected with hookup respectively by screw thread again, hookup shell is connected with shell internal thread by external screw thread again, so just completes the assembling of whole power splitter.

The form that the present invention adopts air cavity to be combined with inner wire, not only can meet the requirement for covering bandwidth, power, and inner wire is not yielding, fidelity is high, reduces the processing request precision in production process simultaneously, thus improves production efficiency.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present invention.

Embodiment:

With reference to Fig. 1, power splitter, it comprises shell 1, merit divides rod 2, hookup 3, arrange meritorious point of rod 2 in described shell 1, merit divides excellent 2 two ends to be connected with hookup 3 contact pin, and shell 1 is connected with hookup 3 shell, described merit divides rod 2 to be divided into two sections, is threaded between two sections by stud.

Described merit is divided rod 2 can arrange 3-5 interface and is connected with hookup 3 contact pin respectively.
