A novel temperature compensated SAW substrate was developed by using direct bonding techniques. This method has merits to keep the same coupling factor and propagation loss as the original piezoelectric substrate and need not strict control of substr

In this paper, we describe a longitudinally coupled double-mode surface acoustic wave (SAW) filter on a 45° X–Z Li2B4O7 (LBO) substrate for 1 GHz radio frequency identification (RF-ID) systems in Japan. Since LBO has a low dielectric constant, the

We present an analytical method of stress and strain in a SAW resonator. This can calculate the absolute values of the stress and strain at each precise point over the resonator for any driving condition and frequency. To represent the SAW resonator,
