Abstract: A dielectric resonator filter operating in a magnetic dipole mode includes a plurality of dielectric resonators disposed in a plurality of dielectric resonator cavities. A plurality of coupling mechanism provide an in-line coupling factor between respective resonators of electrically adjacent dielectric resonator cavities. At least one cross-coupling device provides cross-coupling between respective resonators of non-adjacent dielectric resonator cavities. A magnitude and sign of the in-line coupling factors and the cross-coupling factor, provide a dielectric resonator filter, for which a desired amplitude and phase response can be provided.
