Patent number: 7956708Abstract: A waveguide-type dielectric filter suitable for wideband filter applications made of a metallized dielectric material is provided. The filter includes two or more mutually coupled resonators disposed in a longitudinal manner. The coupling between adjacent resonators is provided and adjusted by slots or through holes. The dielectric block is covered with metal ground coating with the exception of an uncoated area at the input and output that creates two contact pads on one surface of the dielectric block that are electrically isolated from the metal ground coating. Metallized blind holes are formed on the opposing surface of the dielectric block with respect to the contact pads. These blind holes effectively move the ground plane closer to the contact pad, which, in turn increases the coupling between the input and output resonators and external circuitry, which is essential for building wide bandwidth band pass filters.Type: GrantFiled: January 14, 2009Date of Patent: June 7, 2011Assignee: Dielectric Laboratories, Inc.Inventors: David Allen Bates, Mesut Gokten

Patent number: 7663454Abstract: A discrete resonator is provided, including a dielectric base having a dielectric constant. A metal contact formed on a major surface of the dielectric base has a predetermined area and is positioned at a predetermined location on the dielectric base to provide a predetermined loaded Q for the resonator. A metal ground coating is formed on the outer surface of the dielectric base with the exception of an isolation region surrounding the metal contact that is free of the metal ground coating. The area of the isolation region is sufficient to prevent significant coupling between the metal contact and the metal ground coating. The dielectric constant of the material used for the base, and the width and length of the dielectric base are each selected such that the resonator resonates at least at one predetermined resonant frequency in the GHz frequency range.Type: GrantFiled: April 8, 2005Date of Patent: February 16, 2010Assignee: Dielectric Laboratories, Inc.Inventor: David Allen Bates

Patent number: 7449980Abstract: A voltage tunable resonator is provided, including a dielectric base made of a dielectric material having at least one of a voltage dependent dielectric constant and piezoelectric characteristics. A metal contact having a predetermined area is provided on an outer surface of the dielectric base at a predetermined location to provide a predetermined loaded Q for the resonator, and a metal ground coating is provided on the remaining exposed surfaces of the dielectric base, and an isolation region having a sufficient area to prevent significant coupling between the metal contact and the metal ground coating. A control voltage applied between the metal contact and the metal ground coating provides at least one of (i) a variable electric field to control the dielectric constant and a resonant frequency of the resonator and (ii) a piezoelectric response causing a dimensional change in the resonator to control the resonant frequency of the resonator.Type: GrantFiled: February 10, 2006Date of Patent: November 11, 2008Assignee: Dielectric Laboratories, Inc.Inventor: David Allen Bates
