Multifunctional power divider

Abstract

A multifunctional power divider relates to the technical field of power dividers. It includes a shell, a power splitter, and a coupler. The shell is equipped with a power splitter. Both ends of the power splitter are connected to the connector pins, and the outer shell is connected to the coupler shell. The power splitter is divided into two sections. , The two sections are connected by stud threads. The present invention adopts the combination form of the air cavity and the inner conductor, which can not only meet the requirements for coverage bandwidth and power, but also the inner conductor is not easily deformed, has a high degree of simulation, and reduces the precision of processing requirements in the production process, thereby improving 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 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.
