Abstract
A dielectric substrate includes a filter unit, a non-balance/balance conversion unit, and a connection unit for electrically connecting the filter unit to the non-balance/balance conversion unit which are formed in the dielectric substrate. A first resonator has an electrode formed on the main surface of a fourth dielectric layer and a via hole penetrating through a first to a third dielectric layers and connecting the electrode to a grounding electrode. A second resonator has an electrode formed on the main surface of the fourth dielectric layer and a via hole penetrating through the first to the third dielectric layers and connecting the electrode to the grounding electrode.
