Abstract
The utility model discloses a waveguide coaxial changer with coaxial changing waveguide, comprising a waveguide pipe, a ring flange and a coaxial socket connector, wherein, the coaxial socket connector is arranged in a mounting hole on the wide edge outer wall of the waveguide pipe and is coupled through a probe of the coaxial socket connector. The waveguide coaxial changer is characterized in that a medium sleeve end part of the coaxial socket connector is lower than the inner wall of the waveguide pipe so that the inner part of the mounting hole forms an impedance matching section (4). The form of the waveguide coaxial changer is characterized in that the structure is simple, the development cycle is short, the assembling production is easier, the index is better, and the matching is adjusted by the impedance matching section (4) formed between the inner walls, thereby achieving the effects that the bandwidth is expanded evidently, a standing wave ratio is better than the current level, the standing wave ratio in the full range is less than 1.18, and 10 percent of the bandwidth can realize the best effect that the standing wave ratio is less than 1.05.
Description
Technical field
The utility model belongs to electronic devices and components, is specifically related to a kind of waveguide to coaxial waveguide coaxial changer.
Background technology
Now a lot of microwave communication industries need be used waveguide to coaxial conversion, need two port echoes little in the switching process, and the straight-through port loss is little.For easy to use, need in full frequency band, realize.The coaxial switch medium socket of domestic present use waveguide coaxial changer is concordant with waveguide broadside inwall or be stretched in the waveguide.Product nominal standing-wave ratio index be full frequency band less than 1.25,10% bandwidth less than 1.10.Adopt following several matching process, can realize that nominal standing-wave ratio index is less in the full frequency band bandwidth.1. increase probe diameter; 2. probe moves at broadside; 3. introduce ladder on the Narrow Wall of Waveguide limit.The product that 2. 1. method design is difficult to optimize than nominal index again.Method 3. index can design more excellent, pretty troublesome but processing is got up.
Summary of the invention
The purpose of this utility model is to provide a kind of waveguide coaxial changer easy to process, and its bandwidth is expanded obviously, and the standing-wave ratio index is better than present level, and the full frequency band standing-wave ratio is less than 1.1 8, and 10% bandwidth can realize less than 1.05.
The technical solution of the utility model is: waveguide coaxial changer, comprise waveguide, ring flange, coaxial switch, coaxial switch is installed in the waveguide broadside outer wall installing hole, probe coupling by coaxial switch is characterized in that described coaxial switch medium socket end is lower than the waveguide inwall, makes the inner one section impedance matching section (2) that forms of installing hole.Fill the dielectric material of differing dielectric constant in the middle of the described impedance matching section 4, perhaps air.The characteristics of the waveguide coaxial changer of this form are simple in structure, R﹠D cycle is shorter, Assembling Production is easier, index is more excellent, adjust coupling with one section impedance matching section 4 of formation between its inwall and can reach the bandwidth expansion obviously, the standing-wave ratio index is better than present level, and the full frequency band standing-wave ratio can realize best effect less than 1.05 less than 1.18,10% bandwidth.
The utility model can be used in other waveguide in coaxial conversion, can use when needing the Waveguide coaxial conversion such as the input and output of microwave series of products signal.
