A surface transverse wave filter with long interdigital transducers on quartz was experimentally studied. At a frequency of ∼506 MHz, a 3 dB bandwidth of ∼0.3 MHz, an insertion loss of ∼5.3 dB, and a stop band attenuation above 24 dB, were obtained. The amplitude response of this filter was free of spurious transverse and longitudinal modes.
