Abstract
At frequencies above 60 MHz , tuning-free surface acoustic wave (SAW) resonators with many reflectors using Rayleigh SAW are generally used. However, Rayleigh SAW resonators for use in the 60-150 MHz range have some disadvantages such as cost. We have already developed a BGS wave resonator, which is being used commercially in the 30-60 MHz range. When we improved the characteristics of BGS wave resonators by using small-particle , poreless ceramic substrates developed for high-frequency BGS waves, we obtained good resonance characteristics up to 160 MHz. We also obtained good characteristics when we tested the resonator in a DECT demodulator circuit.
