Abstract
Presented are results obtained from acoustic-wave components and devices employing "soldered piezoelectric transducer" technology and operating in the VHF and UHF bands. Based upon the intermetallic diffusion of two layers of indium, deposited beforehand on both the propagation substrate and the piezoelectric transducer, that technology makes it possible to produce transducers having high conversion efficiency. Three types of acoustic components that employ the "SPT" technology are described : dispersive Love-wave delay lines, S-band bulk-wave delay lines and X-band bulk-wave delay lines. In addition, details and results are given regarding oscillators and opto-acoustic deflectors and modulators built using those components.
