[0002] At present, the frequency of the widely used cavity power splitter is between 800-2500MHz, which covers the main frequency of mobile communication, and also covers the general frequency of 3G. Due to the popularization of digital TV, the original analog signal gradually cancels the frequency of 700MHz. The frequency is likely to be used in 3G products. If you want full-band coverage, you need a wider bandwidth bridge and power splitter to cover more frequency bands. Existing power splitters generally use micro Stripline design, its bandwidth is limited, powe...

Embodiment Construction

[0009] refer to figure 1 , cavity power splitter, which includes a shell 1, a power splitter 2, a coupler 3, the shell 1 is provided with a power splitter 2, the two ends of the power splitter 2 are connected with the coupler 3 pins, the shell 1 and The coupler 3 shells are connected, and the power splitting rod 2 is divided into two sections, and the two sections are connected by stud threads.

[0010] The power splitter 2 can be provided with 3-5 interfaces to connect with the connector 3 pins respectively.

[0011] In the present invention, a power distribution rod is arranged in the shell, and the power distribution rod is divided into two sections, one section is 1, 2, 3 grades, which is thinner, and the other section is 4, 5, 6, 7 grades, which is thicker, between the two sections It is screwed and connected to form a whole power sub-rod. Since the length of each section is shortened, the processing deformation is very small, thus ensuring the machining accuracy. Then t...

Abstract

The invention relates to a cavity power divider, relating to the technical field of power dividers. The cavity 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

technical field [0001] The invention relates to the technical field of power dividers. Background technique [0002] At present, the frequency of the widely used cavity power splitter is between 800-2500MHz, which covers the main frequency of mobile communication, and also covers the general frequency of 3G. Due to the popularization of digital TV, the original analog signal gradually cancels the frequency of 700MHz. The frequency is likely to be used in 3G products. If you want full-band coverage, you need a wider bandwidth bridge and power splitter to cover more frequency bands. Existing power splitters generally use micro Stripline design, its bandwidth is limited, power is also very limited, and now there are some designs of cavity power splitters, but they also face bandwidth limitations, it is difficult to exceed the frequency of 700-2700MHz, because once the bandwidth is widened, the inner conductor will If it needs to be lengthened, the rigidity of the inner cond...
