Frequency dependences of signal insertion losses in devices on SAW with piezoelectric acoustic duct

Results of investigation of a signal insertion losses of devices on SAW with piezoelectric acoustic ducts dependence on frequency and width of a passband are given. The technique of experiment is described. The piezoceramic of lead zirconate-titanate system of various marks in structure of delay lines on SAW has been investigated. Nanapozided equidistant interdigital converters (IDC) were used as converters of SAW. The range of frequencies with insertion losses acceptable for passive devices on SAW, and also with an optimal relative passband is determined.
