Embodiment Construction
[0018] The present invention will be further described below in conjunction with specific examples.
[0019] Such as figure 1 and figure 2 As shown, the coaxial cavity dual-band filter provided in this embodiment includes a closed metal cavity 13 and two input and output ports 1, 12; the metal cavity 1 is a rectangular metal cavity, and its internal structure is The linear distribution is the first coaxial resonant cavity, the first coupling resonant window, the second coaxial resonant cavity, the second coupling resonant window, and the third coaxial resonant cavity; the first coaxial resonant cavity, the second The first two resonant frequencies of the coaxial resonant cavity and the third coaxial resonant cavity are the same, and the high-order resonant frequencies are far apart, so that a dual-frequency filter with a wider stop band and better performance can be obtained; the first coupling resonant The positions and parameters of the two parts of the window and the sec...
