Abstract
A band-pass filter for microwave is provided that can be frequency-tuned the filter comprising an input resonator comprising a metal input cavity and an input dielectric element, an output resonator comprising a metal output cavity and an output dielectric element, an input excitation means (S) of elongate shape, an output excitation means of elongate shape, the input resonator and the output resonator being coupled, characterized in that the input dielectric element and the output dielectric element have a recess, the input excitation means penetrates the recess of the input dielectric element the output excitation means penetrates the recess of the output dielectric element, the input dielectric element is capable of carrying out a rotation about an input rotation axis, the rotations of the dielectric elements allowing the modification of the central frequency of the filter.
