Cavity power divider

Abstract

The invention provides a cavity power divider, and relates to the technical field of the power dividers. The cavity power divider comprises a casing, a power dividing rod and a coupler. The power dividing rod is arranged in the casing. Both ends of the power dividing rod are connected with a coupler pin. The casing is connected with the coupler casing. The power dividing rod is divided into two sections which are in threaded connection through a stud. According to the invention, an air cavity and an inner conductor are combined; the requirements of coverage bandwidth and power are met; the inner conductor is not easy to deform and has a high simulation degree; the processing requirement precision in a production process is reduced; and the production efficiency is improved.

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 condu...

[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, it is difficult to guarantee the rigidity of the inner conductor, and it is easy to deform. The difference between the actual trial-produced product and the simulation is huge, and it is difficult to be practical at all, and the processing accuracy is high, which greatly affects the production efficiency.
