Problems solved by technology

[0002] The frequency of the widely used cavity directional coupler 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 to cover the whole band, you need a coupler and a power splitter with a wider bandwidth, so that you can cover more frequency bands. The existing couplers generally use columnar coupling. Although it can cover more frequency bands, it greatly limits the application of this type of product due to its shortcomings such as high production cost, high processing precision, and high assembly requirements.

Abstract

The invention provides a multifunctional coupler, and relates to the technical field of couplers. The multifunctional coupler is composed of a shell, a coupling straight rod, a coupling bent rod, a resistor and a debugging block, wherein the cavity of the shell is internally provided with the coupling straight rod and the coupling bent rod; two ends of the coupling straight rod are connected with the outside through the shell; one end of the coupling bent rod is connected with the outside through the shell, and the other end of the coupling bent rod is connected with the resistor. The multifunctional coupler provided by the invention adopts a coupling stripline quadrupole design, which can not only satisfy the demand of general columnar couplers on cover bandwidth, but also can reduce the processing required accuracy, requirement of assembling and production cost in the production process.

Description

Technical field: [0001] The invention relates to the technical field of couplers, in particular to a multifunctional coupler. Background technique: [0002] The frequency of the widely used cavity directional coupler 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 to cover the whole band, you need a coupler and a power splitter with a wider bandwidth, so that you can cover more frequency bands. The existing couplers generally use columnar coupling. Although the design can cover more frequency bands, its disadvantages such as high production cost, high processing precision, and high assembly requirements greatly limit the application of this type of product.
