Abstract

Radio frequency filters with a narrow band width.and high attenuations are required in recent years. One of the substrates with a suitable coupling factor and an excellent TCF for this filter is a ZnO film/Al electrode/quartz substrate. However, the reflection coefficient of this substrate has not reported, and both the RF SAW filter and the multiple mode resonator one using this substrate have not been reported. In this report, an RF narrow band SAW resonator filter composed of the ZnO/high density metal electrode/quartz structure was realized to obtain a suitable reflection coefficient, and it has minimum insertion loss of 2.08 dB, bandwidths of 3.9MHz (0.054%), and excellent TCF of 4.0ppm/℃.
