The unloaded Q is set by selecting the outside dimensions of the dielectric block. The resonance frequency is set by selecting the size and location of the through-hole as well as the outside dimensions of the dielectric block. A terminal electrode is formed on the outer surface of the dielectric block. A coupling hole is formed in the dielectric block and a coupling electrode is formed on the inner surface of the coupling hole. One end of the coupling electrode is connected to the terminal electrode and the other end of the coupling electrode is either connected to the conducting film formed on the outer surface of the dielectric block or terminated inside the dielectric block.

Abstract: A miniaturized dielectric filter unit exhibiting desired characteristics is formed in which a plurality of resonators are disposed within a dielectric block. A plurality of internal conductors are disposed within the dielectric block. An external conductor and an input/output electrode are formed on an outer surface of the dielectric block. A slit having an electrode therein, which is electrically connected to the input/output electrode, is provided each of between two adjacent through-holes having the internal conductors therein. Thus, unwanted coupling between the input/output sharing filters is prevented, and an external coupling circuit is configured by capacitive coupling. It is thus possible to individually design the respective filters and further to enhance easy designing of the overall filter unit. A transmitting/receiving-sharing unit and a multiplexer, both of which are similar to the above-described dielectric filter unit, are also provided.

The shorting conductor is disposed at a location where the electric field strength of the undesired mode is high.
