Abstract:
A dielectric filter made up of resonators, such that said filter resonates a design frequency, said filter comprising:a three resonator configuration including a #1 resonator coupled to a #2 resonator and a #3 resonator coupled to said #1 resonator and said #3 also coupled to said #2 resonator according to elliptical coupling, one of said #1, #2 and #3 resonators; a first electrical connector connected to said #1 resonator; a second electrical connector connected to said #3 resonator; a band stop resonator coupled to said #1 resonator; and wherein at least one of said resonators between said first and second electrical connector is of a different design from other said resonators, such that said resonator of a different design resonates the same design frequency as said other resonators and resonates different higher order harmonic frequencies than as said other resonators.
