A dielectric filter includes a single block made of dielectric material having three or more through holes in which an inner conductor is deposited to define three or more dielectric resonators coupled in a cascade manner. A reactance coupling arrangement is provided for coupling two spaced dielectric resonators with at least one dielectric resonator between them being skipped. By selecting the value of the reactance coupling arrangement, it is possible to provide a filter having a frequency characteristic in a desired format, including at least one pole at a selected point in an attenuation region thereof, without any increase in the number of stages of the dielectric resonators.
