Abstract

The invention provides a novel cavity power divider, and relates to the technical field of power dividers. The novel cavity power divider comprises a shell, a power dividing rod and a connector. The power dividing rod is arranged in the shell. The two ends of the power dividing rod are connected with the plug pin of the connector. The shell is connected with the shell of the connector. The power dividing rod is separated into two segments which are connected in a threaded way via a screw stud. A mode of combination of an air cavity and an internal conductor is adopted so that the requirements for coverage bandwidth and power can be met, the internal conductor is not liable to deform and simulation degree is high. Meanwhile, processing requirement precision in the production process is reduced so that production efficiency is enhanced.

Description

A kind of Novel cavity type power divider

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 a kind of Novel cavity type power divider, the form that it 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, reduce the processing request precision in production process simultaneously, thus improve 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, a kind of Novel cavity type power divider, it comprises shell 1, merit divides rod 2, hookup 3, meritorious point of rod 2 is set in described shell 1, merit divides excellent 2 two ends to be connected with hookup 3 contact pin, shell 1 is connected with hookup 3 shell, and 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.
