摘要： The present invention provides a dielectric resonator, a dielectric filter, a dielectric duplexer capable of reducing leakage of electromagnetic waves and capable of being miniaturized, and a communication apparatus incorporating the same. In each of the dielectric resonator and filter, inside a dielectric block, there is formed a L-shaped inner-conductor-formed hole having a bend at some point of the hole in a manner extending from an outer surface of the dielectric block to a surface perpendicular to the outer surface. An inner conductor is formed on the inner surface of the inner-conductor-formed hole. On the substantially entire outer surfaces of the dielectric block, there is disposed an outer conductor, with one end of the inner-conductor-formed hole open-circuited and the remaining end of the hole short-circuited. Around the edge of the open-circuited end there is formed an outer coupling electrode. This structure enables formation of the dielectric resonator and the dielectric filter having the L-shaped inner-conductor-formed holes.

摘要： In a dielectric block, an array of three excitation holes, in each of which one opening is a short-circuited end and the other opening is an open-circuited end, are disposed so as to be interdigitally coupled and balanced input-output terminals are provided at the opening of the excitation holes at both ends of the array. A resonator hole is provided so as to be coupled to one excitation hole of the excitation holes at either end of the array. Thus, a compact dielectric filter with balanced input-output terminals is constructed.

摘要： A dielectric filter and a dielectric duplexer having a dielectric block with resonator holes formed therein, each having a large-sectional-area portion and a small-sectional-area portion so that the resonator hole has different respective inner diameters at an open-circuited end and a short-circuited end. Each large-sectional-area portion is formed with the cross-sectional shape of an elongated circle, an ellipse, or a rectangle, for example, the cross-sectional shape defining a longitudinal axis which is disposed at an angle against with respect to a plane in which the resonator holes are arranged. The invention increases the degree of freedom in providing a desired resonant frequency and a desired degree of coupling between resonators, in order to be able to easily provide desired filter characteristics, even in a case in which the external dimensions of the required dielectric block are restricted. Also disclosed is a method of manufacturing the dielectric filter and dielectric duplexer, as well as a radio transceiver utilizing the dielectric duplexer.
