説明

<jats:title>Abstract</jats:title><jats:p>A cognitive radio system, which is being investigated in order to use limited frequency resources effectively, requires a tunable filter with a wide variable frequency range. A wideband resonator is required to realize a tunable filter. It was reported that a resonator composed of a Cu electrode/15° YX‐LiNbO<jats:sub>3</jats:sub> had a large bandwidth of 12%. We attempted to fabricate a one‐port resonator composed of a grooved Cu electrode/4° YX‐LiNbO<jats:sub>3</jats:sub>. This resonator was applied to a tunable filter, and a tunable filter having a tunable range of 6.8% in the center frequency was experimentally realized using a bandpass‐type filter circuit, and one having a tunable range of 9 to 12% was theoretically realized using a ladder‐type filter circuit. © 2013 Wiley Periodicals, Inc.
