- 論文の詳細を見る
Using a flattened SiO2/Cu electrode/36–48° LiTaO3 structure, a small ($5\times 5$ mm2) surface acoustic wave (SAW) duplexer with a good temperature coefficient of frequency (TCF) for US personal communication services (PCS) was realized by the authors. However, a smaller duplexer is strongly required. Using the flip-chip bonding process of SAW chips and a Rayleigh SAW propagating on a flattened SiO2/Cu electrode/126–128° $YX$-LiNbO3 structure, which has a larger coupling factor than the above-mentioned substrate, a smaller ($3\times 2.5$ mm2) SAW duplexer with a good TCF was realized.
