Problems solved by technology

[0002]The frequency of the cavity directional coupler widely used at present is between 800-2500MHz, which covers the main frequency of mobile communication, and also covers the general frequency of 3G Frequency, due to the popularization of digital TV, the original analog signal gradually cancels the frequency of 700MHz, which is likely to be used in 3G products. If you want full-band coverage, you need a coupler and power splitter with wider bandwidth. Covering more frequency bands, the existing couplers generally adopt columnar coupling design, although they can cover more frequency bands, but due to the disadvantages of high production cost, high processing precision, and high assembly requirements, the application of this type of product is greatly limited. application

Abstract

A novel coupler relates to the technical field of couplers. The novel coupler is composed of a housing, a coupling straight rod, a coupling bent rod, a resistor and a debugging block. The cavity of the housing is internally provided with the coupling straight rod and the coupling bent rod. Two ends of the coupling straight rod are respectively connected with the outer parts through the housing. One end of the coupling bent rod is connected with the outer part through the housing, and the other end is connected with the resistor. According to the invention, the coupling stripline four-level design is adopted, the coverage bandwidth requirement of a general cylindrical coupling rod bridge is met, and the machining precision, the assembling requirements and the production cost in the production process are also lowered.

Description

Technical field: [0001] The invention relates to the technical field of couplers, in particular to an air cavity stripline 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. Invention content: [0003] The purpose of the present inventi...
