Wide bandwidth of 30MHz was achieved by 3-IDT SAW resonator filters using 36Y-X LiTaO3 substrates at 800MHz. The filter, which has fractional bandwidth of 3.6%, can be applied for several mobile communication systems. Low insertion loss of 1.7 dB was obtained by taking parallel arranged configuration, which proved to be 0.4 dB better than simple cascade-connected configuration.
