Abstract
PURPOSE:To facilitate the manufacture of the titled device, to make a branching filter circuit smaller and lighter, and to lower its costs by providing an inductor and a capacitor in the branching filter circuit. CONSTITUTION:A mounted filter N129 for transmission and a filter N230 for receiving are composed of a homogeneous dielectric of a single body, connected with plural dielectric resonators 31 and 36 consisting of cylindrical central conductors built in the dielectrics at a prescribed interval, and with the central conductors of the respective dielectric resonators 31 and 36, provide plural frequency adjusting patterns 32 and 37 formed on one side surface, and coupling quantity adjusting patterns 33 and 38 between the frequency adjusting patterns 32 and 37, and further, by using the rear surface of a substrate 20 and forming a fine line, form an inductor LRT42, a capacitor CRT43 and an inductor LTE44. Thus, the manufacture of the branching filter is facilitated, the branching filter is made smaller and lighter, and its costs are lowered.
