摘要： A method which is capable of easily obtaining specified filter characteristics in a short time, even in the case of a dielectric filter having complicated relationships between changes in the filter characteristics and the amount that a specified part of a dielectric member or a dielectric film is trimmed. In the dielectric filter, data is obtained in advance showing the relationships between the amounts that specified parts of a conductive film or a dielectric member are trimmed, and the corresponding changes in the values of a center frequency and a coupling coefficient between resonators. Further, adjustment values are obtained from the initial characteristics of the dielectric filter to be adjusted, and then, the targeted amounts of trimming are obtained from the adjustment values, targeted adjustment values, and the aforementioned data concerned so as to perform trimming.

摘要： A filter unit comprises a wideband bandpass filter; at least one band-elimination filter having a stop band within the passband of the bandpass filter, so that the passband is divided into a plurality of pass bands by the stop band; and the wideband bandpass filter and the band-elimination filter being disposed in a single dielectric member. Since the passband of a wideband bandpass filter is divided into a plurality of pass bands by stop bands of one or more band-elimination filters, signals having frequencies corresponding to these divided pass bands are able to pass through the filter unit simultaneously.

摘要： Inner conductor formation holes having inner conductors formed on the inner walls thereof are formed in a dielectric block. Both of the ends of one of the inner conductors are open and led out as terminal electrodes which function as balanced ports. Both of the ends of another inner conductor are connected to an outer conductor to be grounded, and the center portion of the inner conductor between the ends is led out as a terminal electrode which functions as an unbalanced port. The circuit can also be realized with striplines or microstriplines on a dielectric substrate. Thus, a balanced-unbalanced converter having these terminal electrodes as balanced and unbalanced ports is formed.
