  • Abstract
    Grating-array transducers are used to launch acoustic surface waves at 2.55 GHz on a LiNbO3 substrate. The insertion loss of a 1.5 ¿s delay line is equal to 39 dB with matching stubs at input and output. The 3 dB bandwidth is equal to 87 MHz. For this frequency range, array transducers are easier to fabricate than standard interdigital transducers. Performances of the two types of transducers are compared.
