High-stability SAW oscillators with cubic frequency temperature curve and excellent aging characteristics

Autor: Takao Morita, Shigeo Kanna, Yoshio Maeda, Kunihito Yamanaka, Naohisa Obata

Publikováno v: 2010 IEEE International Ultrasonics Symposium.

We describe the realization of oscillators combined with quartz's innate excellent long-term stability of frequency and frequency temperature characteristics by optimization of SAW oscillator's design conditions using quartz crystal substrates in app

Development of fundamental components for amplification of magneto-surface-acoustic-waves in highly magnetostrictive metal films by means of electron bunching

Autor: Takeshi Kawahata, Mitsuteru Inoue, Naohisa Obata, Hironaga Uchida, Kazuhiro Nishimura

Publikováno v: MRS Proceedings. 785

In a magneto-surface-acoustic-wave (MSAW) device, phase velocity is controlled by an external magnetic field. We proposed amplification of MSAW with a hybrid structure of FeB amorphous film / InSb semiconductor thin film / LiNbO3 substrate, which is
