ABSTRACT:
A λ/2 resonator comprises an inner conductor formed hole having an inner conductor with both open-ends, formed therein, and λ/4 resonators comprise inner conductor formed holes having inner conductors with one short-circuited ends and the other open ends, respectively. The resonators are coupled, whereby a terminal electrode connected to the vicinity of the one open end of one of the λ/4 resonators functions as an unbalanced terminal, and terminal electrodes connected to both open ends of the λ/2 resonator function as balanced terminals.
