Abstract

PURPOSE:To prevent the occurrence of the spurious response cuased by the combination of the unnecessary modes through a simple constitution, by securing the space between the bottom surface of the dielectric and that of the box at the area where the dielectric resonator. CONSTITUTION:The microwave filter contains dielectric 2 on which dielectric resonator 5a, 5b and 5c are mounted plus metal box 1 with dielectric 2 mounted close on its bottom surface. Then frequency control screws 6a-6c plus input electrode 3 and output electrode 4 are formed to box 1. Space 7 is then formed between the bottom surface of box 1 and the area where at least one unit of dielectric resonator 5b are mounted, thus preventing the occurrence of the spurious response cuased by the combination of the unnecessary modes.
