Dielectric filter having coaxial resonators and a notch pattern |
摘要 |
A dielectric filter having two outside resonators, one middle resonator disposed between the two outside resonators, and a notch pattern is provided. An input pad and an output pad are formed within respective non-coated lateral areas of a lateral surface corresponding to the outside resonators, respectively. The notch pattern is formed within an expanded non-coated lateral area of the lateral surface coupled to one of the non-coated lateral areas of the lateral surface which corresponds to a third position of the lateral surface corresponding to the middle resonator and one of the outside resonators. The notch filter is extended along the lateral surface from the input pad or the output pad toward the middle position corresponding to the middle resonator. The notch filter forms an electrical capacitor between the middle resonator and the input pad or the output pad.
