Embodiment 1
[0024] Such as figure 1 As shown, a coaxial resonant cavity hybrid coupling method includes a conductor shell 1, and two resonant cavities 6 are opened in the conductor shell 1, and the top of the conductor shell 1 is sealed by a conductor cover plate 10; each resonant cavity 6 includes a conductor Resonant rod 7, the upper end of the conductor resonant rod 7 has a cavity, the lower end is a rod body structure, the conductor resonant rod is cylindrical, the upper radius of the conductor resonant rod 7 is large, the lower radius is small, the cavity is at the upper end of the large radius, and the conductor resonant rod 7 The bottom end is fixed in the resonant cavity 6 by fastening screws 8, forming a vertical structure with the bottom surface of the resonant cavity 6, the conductor resonant rod 7 is a conductor, and contacts with the conductor shell 1 to form a short circuit; there is a tuning screw 3 on the conductor cover plate 10; the tuning screw 3. Adjust from top to bot...
Embodiment 2
[0027] The same coaxial resonant cavity hybrid coupling method also includes a conductor shell 1, and two resonant cavities 6 are opened in the conductor shell 1, and the top of the conductor shell 1 is sealed by a conductor cover plate 10; Including a conductor resonance rod 7, the upper end of the conductor resonance rod 7 has a cavity, the lower end is a rod body structure, the horizontal section of the conductor resonance rod is quadrilateral, the upper and lower radii of the conductor resonance rod 7 are the same, and the bottom end of the conductor resonance rod 7 is fixed by fastening screws 8 In the resonant cavity 6, it forms a vertical structure with the bottom surface of the resonant cavity 6, and the conductor resonant rod 7 is a conductor, which is in contact with the conductive shell 1 to form a short circuit; there is a tuning screw 3 on the conductor cover plate 10; the tuning screw 3 adjusts the extension guide from top to bottom In the cavity at the upper end ...
