In microwave system, often use the most universal a kind of parts, the transition element of another kind of transmission line is i.e. transformed to by a kind of transmission line, it is referred to as waveguide switch, for impedance matching good in realizing broadband, now widely used broadband coaxial rectangular waveguide transducer, mainly has two kinds of forms, probe-type and Ridge Waveguide Transitions formula.Probe-type, the coaxial inner conductor top that will insert waveguide cavity connects upper rosette or ball, and arranges some tuning screws in waveguide cavity.Ridge Waveguide Transitions formula, by adding JIPIAN in the waveguide, forms stepped impedance transformer, makes the output impedance characteristic impedance close to coaxial line of ridge waveguide, to reach the purpose of impedance matching.Current coaxial converter return loss in all-wave conduction band width is big, and needs multistage conversion, and volume is relatively big and processes and handling inconvenience.
Utility model content
The shortcoming of prior art in view of the above, of the present utility model aim to provide a kind of in all-wave conduction band width return loss little, be not required to multistage conversion, compact conformation, overall dimensions is little, easy to process, load and unload easy waveguide coaxial converter.In order to achieve the above object, this utility model is achieved through the following technical solutions:
A kind of waveguide coaxial converter, including square wave guide cavity, inner wire, probe, medium socket, coaxial connector joint, tuning screw, inner wire bottom hangs with the rosette that radius is its twice, inner wire is connected on square wave guide cavity, probe is placed in the interior medium socket of inner wire and entangles, tuning screw is placed in rectangular waveguide intracavity, it is characterised in that: described tuning screw is two.
Preferably, described probe is ladder probe, and chamfering, electroplate are arranged at top.
Preferably, described square wave guide wall is aluminium sheet.
Above-mentioned a kind of waveguide coaxial converter, its tuning screw is placed in probe side, and described probe is 45 millimeters with the distance of rectangular waveguide cavity wall, and the distance of two tuning screws and probe is respectively 35.8 millimeters, 69.5 millimeters.
Above-mentioned a kind of waveguide coaxial converter, described tuning screw is placed in probe both sides, and described probe is 45 millimeters with the distance of rectangular waveguide cavity wall, and the distance of two tuning screws and probe is respectively 35.8 millimeters, 69.5 millimeters.
The waveguide coaxial converter that this utility model provides, use the different size of inner conductor structure of upper-lower section, ladder probe and the design of two tuning screws, again through Experimental Comparison, set probe distance rectangular waveguide cavity wall, the optimal design distance of two tuning screw distance probes, in making its all-wave conduction band width, return loss is low, and it is little, easy to process to need not multistage conversion, compact conformation, volume.
