Applications of edge-bonded transducers to SAW components

Various applications of the EBT to acoustic devices are reported. First we describe the operation of these transducers in the case of Rayleigh waves. Then we report the results we have obtained in the fabrication of: 1) a piezo-MOSFET programmable filter with a bit rate reaching 50 MHz; 2) a Love wave-dispersive delay line with a 240 compression ratio; 3) a fused silica reflective array compressor exhibiting a 30-µs dispersion over a 60-MHz bandwidth around 100 MHz and a 24-dB total insertion loss.
