Abstract

PURPOSE:To realize a small size for a branching filter as well as a reduction of the number of component parts, by providing the branching point to one end of the filter having the lower frequency among the filters having different central frequencies and then connecting the branching point to one of the terminals. CONSTITUTION:The grooves 4 and 5 are provided in the direction of the longer side in the case 1, and the dielectric resonators 8-15 plus 16-21 are stored in a row each into the grooves 4 and 5 respectively. The resonator 15 at the end part and the resonator 21 are connected to the terminals 39 and 40, respectively. And the resonator 8 is connected to the terminal 41 via the strip line 46. Furthermore, the resonator 16 is connected to the connection point 48 at the middle of the line 46 via strip line 47. Then the central frequencies of the filters consisting of the resonators 8-15 and 16-21 are set to f1 and f2 respectively. And the length of the line between the branching point 48 and the resonator 16 is set longer than that between the point 48 and the resonator 8. As a result, the signals of frequencies f1 and f2 are supplied and delivered only between the terminals 39 and 41 plus the terminals 40 and 41 respectively.
