Two kinds of manifold type and cavity step conversion formula.
1) probe manifold type, the i.e. inner wire of coaxial connector are equivalent to probe and are inserted into waveguide cavity just from waveguide broadside
Knot structure motivates TE moulds, to improve matching performance, in the inner wire bottom of coaxial connector welding allotment column, to adjust wave
Shape realizes impedance matching.The advantages of structure is simple easy processing, in certain frequency band, voltage standing wave ratio can reach≤
1.25, but need to adjust welding allotment column, therefore production efficiency is relatively low and more demanding to debugging.
2) cavity step conversion formula, the i.e. inner wire of coaxial connector are inserted into the ladder of step waveguide intracavitary from waveguide broadside
In, which can effectively reduce impedance in the case where increasing bandwidth, obtain preferable Performance Match；For step conversion, need
Want accurate simulation calculation and mechanical processing；Requirement for high frequency, since the inner wire size of coaxial connector is smaller, ladder
On the positioning of hole difficulty, processing also is difficult to ensure, processing cost improves；Also it is that the assembly in later stage and debugging bring very big be stranded simultaneously
It is difficult.
