Method for producing dielectric resonator apparatus having metallized mesa

A method of altering resonant characteristics of a dielectric filter, the method comprising the steps of:

• forming a volume of dielectric material having first, second, and side surfaces, at least said first surface further having a plurality of protuberances disposed substantially collinearly thereon;
• forming a plurality of holes in said volume, such that at least a first of said holes extends substantially from the apex of a first protuberance on said first surface through said dielectric material to said second surface;
• coating said first, second, and side surfaces of said volume, at least said first protuberance, and an interior surface of at least said first hole, with a conductive material;
• removing at least a portion of the conductive material from at least said first protuberance, such that a mesa having physical dimensions is formed by said first hole and said first protuberance, and thereby forming a dielectric filter having frequency response characteristics;
• and
• altering the physical dimensions of the mesa such that the frequency response characteristics of the dielectric filter are changed.

• removing at least a portion of the conductive material from at least said first protuberance, such that a mesa having a predetermined height is formed by said first hole and said first protuberance, and thereby forming a dielectric filter having frequency response characteristics;
• and
• mechanically grinding a portion of the mesa, thereby reducing the predetermined height, such that the frequency response characteristics of the dielectric filter are changed.
