摘要： A temperature compensated filter comprises a block (1) of dielectric material having at least one transmission line resonator (3) formed herein. All surfaces except one side surface of the block are substantially coated with an electrically conductive layer (11). For achieving temperature compensation, a capacitor (6) coupled to the conductive layer (11) through a strip line (7) is attached, in a heat conductive way, to the uncoated side surface of the dielectric block. The capacitor (6) tunes the main resonator and the temperature dependence of its frequency is opposite that of the dielectric body so that it compensates the temperature dependence of the frequency of the main resonator.

摘要： A dielectric filter is formed from a block of ceramic material with holes extending from a top surface toward a bottom surface. At least the bottom, both ends and one side surface are coated with conductive material. Also, the interior surfaces of the holes are coated with conductive material to form transmission line resonators. The uncoated side surface has an electrode pattern which allows coupling to the filter and between resonators of the filter. The elevation of the electrodes on the side surface between the top and bottom determines whether the coupling is capacitive, mixed inductive and capacitive, or inductive.

摘要： The invention relates to a resonator structure comprising a helix resonator (1) wound of metal wire into a cylindrical coil and supported by a plate (2) of insulating material disposed therewithin. A helix resonator is usually made in the form of a cylindrical coil and supported by disposing within the coil a frame made of a ceramic material or plastic in various ways. This is necessary for providing a sufficient mechanical strength. However, such a structure is difficult and expensive to manufacture in series production especially with smaller resonator sizes. These problems are solved by means of a resonator according to the invention in such a manner that at least a part of the insulating plate (2) comprises an electrical circuit formed by strip lines (3), and that the helix resonator (1) is electrically connected to said circuit.
